5. SCREEN MAKING:
Engraving of covert includes next six steps

  1. Unpacking
  2. Rounding
  3. Degreasing
  4. Washing
  5. Drying
  6. Coating

5.1. UNPACKING:
The outset step inwards the grooming of concealment for engraving is unpacking of screens. Screens are ordinarily received in a bean shaped package from which they are carefully taken out so that no dent is generated in the covert. It’sec advised not to go along screens inwards the boxes for more than a twelvemonth otherwise they can crusade problems inward rounding process together with too not more than 4 screens should be kept on i another because weight of the screens tin can campaign serious problems. While taking out concealment from the packaging tending of its dimensions are taken in addition to we brand certain that the screens are more than towards rounder cast.

five.ii. ROUNDING:
In guild to convey cover inward circular form, rounding rings are used. On both sides of concealment, rounding rings are inserted and so screens are pose inward polymerization bedroom. Polymerization process for rounding of concealment is done at 180 to 200°C for ten to xv minutes. After polymerization, rounding rings are removed from covert. Screens packed inward boxes take a fiddling larger size and so the measure ane. After polymerization, screens are put over a stand and then they are cutting into master copy size through a scissor. After it, concealment both ends are taped with the help of a paper tape so that no treatment score seem on covert during coating.

v.3. DEGREASING:
To become fifty-fifty coating throughout the cover degreasing of concealment is done with emulsion SCR 35. Ratio is kept one:4 which way 4 times H2O in addition to one fourth dimension emulsion. The fourth dimension allowed is v to x minutes. Soft H2O is always used patch making an emulsion.

5.4. WASHING:
For the procedure of washing showering of screen is done, iv times from superlative to bottom than bottom to tiptop alongside soft water. If soft water is not used than carbonates will stick to concealment and that constituent of concealment will not polymerize.

v.5. DRYING:
The process of drying is carried out inwards dirt complimentary room. It’s advised to acquit drying at coldness around 20°C. Clamps are e’er used to hold the covert.

five.vi. COATING:

The process of coating is normally done to close the meshes of concealment. The screens are placed inward cones together with plate containing coating cloth which moves downwardly tardily entirely ones. The exclusively two chemicals used for concealment coating are SCR 102 in addition to SCR 101. SCR 102 is the Lacquer too it is a universal emulsion. SCR 101 is a sensitizer in addition to it is too an emulsion.

Recipe for coating solution is equally follows:

SCR 102
1000gm
SCR 101
50gm
Water
100gm

After coating, screens are lay inward clamitizer, around twenty screens could be placed in 1 clamitizer. Coated screens are dried in clamitizer through air. 20 minutes are required for drying ane coated cover. In instance of using max wax jet engraving motorcar, concealment should brought for engraving immediately later clamitizing otherwise cover volition go hard. But in instance of using Light Amplification by Stimulated Emission of Radiation jet engraving automobile, later on clamitizing screens are polymerized at 200°C for i – ane.v hours. The polymerized screens should convey for engraving within ane hour. The peak ends of coating sleeping room are covered with tape otherwise emulsion may catamenia within walls of bedroom. Two squeegees are always used, i for coating together with other for scrapping.

Faults Or Defects Of Screen Printing Too Roller Printing

Screen printing:
Screen printing is ane of the pop printing techniques. It is an quondam historic period process. Different screen is needed for each color. In this printing method, meshing is used to transfer ink onto a substrate, except inward areas made impermeable to the ink past a blocking stencil. H5N1 blade or squeegee is moved across the concealment to fill up the open meshwork apertures alongside ink, in addition to a opposite stroke and so causes the cover to impact the substrate momentarily along a business of contact. During screen printing procedure or so common defects come about. Important covert printing defects, causes too remedies are explain below.

 is one of the popular printing techniques Faults or Defects of Screen Printing and Roller Printing
Fig: Screen printing

Screen printing defects:

ane. When uneven pressure level is exerted past the squeegee during the stroke, the resulting print becomes lighter on i selvedge together with becomes gradually deeper towards the other. Uneven steaming may as well atomic number 82 to this mistake.

two. The prints may come up out lighter inward the eye in addition to deeper towards the selvedges. This occurs when likewise much cloth is steamed inward 1 batch or when the cloth is very thick.

three. Very small-scale specks of color appear on the ground (unprinted portions) when the covert has tiny holes inwards the blocked areas. In this example, the cover should live inspected and lacquer applied at these places.

iv. When the printing has likewise much solids in it, specially inwards paint printing, the cover may got choked during working. This results inward light prints subsequently working for roughly time.

5. When the concealment is placed on a previously printed expanse amongst some other color, which is non dried, the back of the covert picks up more or less glue as well as transfers it to the adjacent area where it is placed, leading to smudging of the print.

half-dozen. Deeper prints are obtained irregularly throughout the cloth. This may due to uneven table surface in addition to thence the squeegee exerts different pressures at different places.

seven. Deeper prints seem throughout the material in the management of the weft (management of the squeegee stroke). Uneven border of the squeegee leads to this mistake. This may remedied by sharpening inwards the squeegee border.

viii. If the squeegee vibrates spell applying the pressure level deep stripes along the warp look.

ix. When a glue containing a big sum of foam is printed, lighter prints are obtained throughout the material.

10. Lighter prints occurring irregularly may live due to uneven application of eh mucilage patch fixing fabric on the tabular array.

eleven. If a soft tabular array is used on a hard tabular array surface deeper prints are produced. On the other hand, if a difficult squeegee is used on a soft tabular array surface, fine lines of the designs are not obtained.

Roller printing:
Roller printing is i of the almost economical too fasted style of printing. It is likewise called straight printing. Influenza A virus subtype H5N1 sort out dye paste for each colour is applied to the material from a metal roller that is intaglio engraved according to the pattern. Designs alongside upwards to sixteen colors introduce no job inward roller printing. Common causes and remedies of roller printing are given below:

Roller printing defects:

one. When grit particles in the printing paste cut the smooth surface of the unengraved roller, the scratches produced will besides transfer the paste to the cloth. By burnishing the roller besides every bit by straining the printing glue once again this mistake may live removed.

ii. Sometimes large double stripes of color called snappers look along the length of the material due to firm coming under the color physician edge. Washing, cleaning the doc blade, roller as well as filtering the paste are to forbid this defects.

three. Very minute snappers called litts are produced at regular intervals on the material because of particles of steel getting embeded inward the engraving of the roller. Cleaning the roller engraving can prevent this mistake.

4. Streaks look equally fine lines or serial of lines running along the piece as well as parallel to selvedge due to scratches on the engraved roller together with cutting in the color physician blade edge. Polishing the roller in addition to sharpening the MD blade border tin remedy this job.

5. Scumming is the fault arising out of insufficient scraping of the printing glue from the unengraved component part of the printing roller past the physician blade.

6. Uneven printing is some other error due to the faulty of the material, the roller, the printing paste too working of the motorcar.

7. The printed textile with deeper shades nearly one selvedge than most the other due to uneven pressure exerted past the engraved roller on the pressure bowl too faulty setting.

viii. If the plumbing equipment of the engraved roller on the mandrel is not perfect, it slips spell rotating, this defect known every bit lobbing of the engraved roller.

Departure Betwixt Rotary Cover Printing Together With Roller Printing

Rotary Screen Printing:
Rotary screen printing is a continuous printing procedure. H5N1 perforated cylinder or spherical cover are used which are automatically fed amongst glue from inside by especial pump. Each concealment is independently driven. The transfer of printing glue through the perforations of the screen into the fabric is governed by specially designed mash blades. During printing, the glue is pressed through the surface via openings inward order to obtain the desired blueprint. The cylindrical screens allow more screens to be arranged per unit length than is the instance with flat screen printing. Speed range from xxx to fifty metres/minute. The touchstone internal circumference of cylindrical screens is 640 – 640.1 mm. However, other dimensions· are likewise possible. Production efficiency of rotary cover printing is high though printing toll is high due to high toll of screen. Besides, unlike screens are needed for varying colors.

Roller Printing:
Roller printing is the near economic as well as fastest mode of printing techniques. This type of printing is also referred to equally intaglio or machine printing. The technique of roller printing is especially used for very large batches but faces swell contest from rotary covert printing. Roller printing is capable of producing really abrupt outlines to the printed design which is specially important for pocket-size figures. The maximum blueprint repeat is the circumference of the engraved roller. Designs alongside upward to xvi colors acquaint no problem inward roller printing.

Printing Glue Ingredients Together With Their Functions

Ingredients of Printing:

Printing way localized application of dyes on the fabric according to pattern. For printing it is required to create printing paste. Printing glue is a gluey paste which is made from pigments, thickeners in addition to many of chemical. H5N1 proficient printing glue is mainly responsible for skillful printing effect. So it is really important to make a printing glue. There are unlike types of ingredients are used to brand printing glue.

  9. Career as well as swelling agent.
  10. Miscellaneous agent

Printing Paste Ingredients as well as their Functions:

one. Dyes/Pigments:

Functions:

  • Attraction of dyestuff to the fiber due to presence of auxochrome.
  • To attain color consequence on the textile.
  • To produce required shade.

Example: Vat, Azoic, Reactive, Direct dye etc.

2. Wetting agents:

Functions:

  • To wet the textile as well every bit dyestuff.
  • To cut surface tension of H2O allowing the dyestuff for slowly penetration into fiber.
  • To obtain smooth paste.
  • To dissolve the dyestuff inwards the paste.

Example: Olive crude, T.R crude oil, Caster rock oil, Lissapol north, Animal rock oil, Glycerine.

iii. Solvents/Dispersing agents/Solution acids:

Functions:

  • To get brilliant design,
  • To assistance dye penetration,
  • To spread dye molecules evenly in the paste,
  • Assist dye fixation,
  • To forbid aggregation of dye molecules inwards the highly concentrated of the dye.
  • To forbid precipitation.
  • To increase solubility of the dyes.
  • To make proper printing shade.

Example: Urea, Glycerine, Desirable, Alcohol, Acetone, Diethylene glycol, Thio diethylene glycol.

iv. Thickener:

Functions:

  • To hand required viscosity to the printing glue
  • To prevent premature reactions between the chemicals contained inwards the print glue.
  • To hold the ingredients of the print glue on the cloth.

Example: Na-alginate, Fine mucilage, British gum, CMC.

v. Defoaming agents:

Functions:

  • To prevent the foam generation during printing.

Example: Silicone, Defoamers, Sulphated rock oil, Perminol KB, Emulsified pino fossil oil.

six. Oxidizing agents:

Functions:

  • To educate the concluding color during steaming or in the subsequent after handling.
  • Assists to dye fixation.

Example: Sodium chlorate, Potasium chlorate, Sodium nitrate, Resist common salt, Ammonium chlorite, Ludigol, Na or M dichromate.

seven. Reducing agents:

Functions:

  • Used for reduction of dissimilar dyes.
  • Used for mainly inward discharge printing.
  • To destroy colour from the ground of material.
  • To make the insoluble dyes to soluble.

Example: Sodium hydrosulphite, Stanus chloride etc. Rongolite-C.

8. Catalyst as well as oxygen carrier:

Functions:

  • To prevent fiber damage during steaming.
  • Accelerate the final colour development by oxidation.
  • Reduce the adventure of oxidation.

Example: Copper sulphide, Ammonium vanadate, Potassium ferrocyanide.

nine. Acids/Alkalis:

Functions:

  • To keep pH.
  • To educate the colour or printed material.
  • To make dye on the textile permanently.

Example: Organic acid, Alkali KOH, NaOH, Na2CO3, Pottasium carbonate, Sodium bicarbonate, Sodium acetate.

x. Swelling agents:

Functions:

  • To make the large size holes of the fibers.
  • Helps to bully the fiber construction.
  • To reduce crystallinity.
  • Help the slowly penetration of dye molecule inside the fiber polymer.

Example: Polyethylene glycol, Phenols, DEGDA (Di-ethylene glycol diacetate)

11. Carrier:

Functions:

  • Used for fixing disperse dyes on polyester or polyester wool blends at temperature below 105oC.

xiii. Mild oxidizing agent:
During steaming of ago colour, the partial color tin live destroyed by the issue of reducing. To secure of this status, mild agent is used.

Example: Ludigol, Resist common salt.

Styles Of Printing Or Printing Styles

Printing:
Printing is the method of localized application of dyes or pigments that create detail colour outcome on fabric according to pattern. The deviation of this procedure alongside dyeing is the overall/throughout coloration where every bit printing is entirely localized coloration.

Styles of Printing:
The diverse processes past which fabrics are printed with unlike types of chemicals are meant the styles of printing or print manner. There are diverse styles of printing available among which next are the almost important.

  Influenza A virus subtype H5N1. Direct manner
  B. Discharge way
  C. Resist manner

Influenza A virus subtype H5N1. Direct printing way:
The direct fashion is the easiest too to the lowest degree expensive of the 3 chief printing styles. It involves the printing of a pattern with dyes direct onto white material. This way is suitable for the printing of both unproblematic too complicated designs; colour matching with the original pattern is also slow. Thereby, this is the virtually popular together with about extensively used way for bulk produced printed fabrics.

B. Discharge fashion of printing:
The literal significant of the word “discharge” is to eliminate or to take away. It agency the way of printing which can make a white or colored outcome on a previously dyed cloth earth.

This discharging of colour from previously dyed ground is carried out past a discharging agent, which is capable of destroying colour past oxidation in addition to reduction.

The discharging agents are – oxidizing agent (1.e. Potassium chlorate, Na-chlorate etc.) or reducing agent (i.e. Rongalite-c, Stannous chloride etc.)

Discharge Printing Methods

Discharge Printing Methods” />Fig: Discharge printing on t-shirt

Methods of Discharge Printing:
Basic steps of discharge printing are printing, drying, steaming as well as washing. This technique is used on dyed fabrics (usually inwards nighttime shades). The fabric is dyed inwards the slice as well as then overprinted amongst a discharge glue (chemic) that destroys or decolorizes or changes the colour inward designed areas. Influenza A virus subtype H5N1 white discharge is when the master copy white is restored to the printed expanse. A colour discharge is when a classify colour is applied at the same time as the discharge glue. Sometimes the base colour is removed together with some other color is printed inwards its place; but normally a white surface area is desirable to brighten the overall blueprint.

This printing method is by and large used to obtain designs alongside tiny details, sharp together with well defined edges on colored backgrounds, patterns alongside low coverage ratio on colored backgrounds, in addition to to avoid blueprint matching problems on endless blueprint patterns alongside colored backgrounds. The results obtained alongside this printing method could live hardly reproducible amongst directly printing since it would live real hard to obtain wide backgrounds, shine together with good penetrated, alongside abrupt edges without seam defects.

H5N1 job for this printing method is represented past the ask to pick out perfectly destroyable dyes for backgrounds, which cannot live affected by the discharging agent used as brightener. The choice restricts the number of applicable dyes as well as higher up all, for around color classes, really few dyes grant a skillful fastness to low-cal and moisture, merely splendid colour effects. With this type of printing carried out on black or navy blue backgrounds it is besides impossible to bank check if the various colors are correctly positioned; whatsoever fault volition live visible entirely subsequently the steaming procedure as well as at that point it would live impossible to correct it. This job could be limited past testing the printing upshot on a white fabric earlier kickoff the printing process.
