83.0 Purpose: This process produce maximum output of printing.
ü  This process is done to increase the attractiveness of customer.
83.1 Scope: This process is applicable for printing unit.
83.2 Responsibility: Quality Control In‐charge, Manager Production, Color master and Manager Store are responsible for ensuring that this procedure is followed during operation.
83.4 Procedure: Puff print is another common print in the fashion industry. Sometimes it called emboss print also. It is almost similar to the rubber print we can make this print in any color. In puff, print rubber and puff chemical used combined. Mainly buyer asked this print on this print on knitted T-shirt. The printing process is same as other serene print. One of the original specialties affects in the world of screen-printing. Puff ink is a plastisol that has been modified with the addition of a heat reactive foaming agent. The ink expands when exposed to high temperature heat as the garment is cured.[8] An additive to Plastisol inks which raises the print off the garment, creating a 3D feel. In this method when the paste is printed and dries it look like normal printing garments but once it is cured the prints gets raised from the surface of fabric.
Printing process:
ü  Like as other print we make the print screen at first.
ü  We make rubber color as manual.
ü  Mix an Emboss or Foaming paste with the following color.
ü  Then print on the garments with following color mixer like as a normal rubber print.
ü  Then we dry the print area by using heat. This the turning point of the print. Because after getting the heat the print becomes puffed. Normally we dry the print area with dryer for small print. If the print area is larger than we heat press the print with curing machine. It will make the puffed evenly, before heat press please adjusts the temperature and pressure of curing machine to get the correct output. Less heat will give you a less puffed print.

Glitter Printing Process

Glitter Printing Process

84.0 Purpose: To make a new design & lucrative for the customer.
84.1 Scope: This process is applicable for printing unit.
84.2 Responsibility: Quality Control In‐charge, Manager Production, Color master and Manager Store are responsible for ensuring that this procedure is followed during operation.
84.3 Definition: Glitter is a unique, clear digital print and cut material for full-color printing that adds the bold look of sparkly glitter. Glitters add on the garment with paste and fixed by heat on a specific area. This is a clear material with flakes of glitter built in. Glitter is excellent for small designs and detailed logos and is compatible for use with Eco-Solvent, Solvent, Latex, and thermos resin inks.


Glitter describes an assortment of small, flat, reflective particles. Glitter reflect light at different angles, causing the surface to sparkle or shimmer. Glitter is like confetti or sequins, only smaller. Since prehistoric times, glitter has been made and used as decoration, from many different materials including stones such as malachite, galena, mica, insects, and glass. Modern glitter is usually manufactured from plastic.

Glitter printing enables the fabric to show glittering granules on the fabric. For this Glitter, powder is used. Glitter Powder is generally PET with size of 1/8" to 1/256". It is cut into square and hexagon shape. It is available in metallic, rainbow, laser and iridescent colors. Generally, it comes in 25 kg bag. A typical glitter power substance is heat resistant to 170-degree Celsius and is acid and alkaline proof. The picture of the glitter powder is as given below:






Foil Printing Process



85.0 Purpose
85.1 Scope This process is applicable for printing unit.
85.2 Responsibility: Quality Control In‐charge, Manager Production, Color master and Manager Store are responsible for ensuring that this procedure is followed during operation
85.3 Procedure: Foil is actually a heat press application, but can be applied on press for certain affects. Foil adheres to plastisol inks or a clear foil adhesive. Available in silver, gold, bronze, red, and blue. There are some awesome iridescent foils affects available too - just check with your sales rep.[1]To get the gold /silver stamp, a foil layer is affixed to a certain material by a heating process. It is not too complicated of a process and getting the files ready are quite similar to uv-spot printing. See my guide on preparing files for print as a reference and talk with your printer about how to supply the files. In foil printing, the quality of the adhesive is very important. Generally, it is made up of acrylic co-polymer with water as diluents. Cheaper qualities show very poor stretch, loss of softness and smoothness after five washes and look very unlike the original print. The foil should not stick to cured inks under pressure.
 In the second method, printing is done on the foil paper first, and then foil is pressed on the fabric with hot steel roller or iron. Foil paper is called the stamping foil paper. Actually, it is not the paper but the detachable foil film on the plastic base.
Recipe: It is a simple recipe; this recipe can be charged on the depth of the color and types of dyes use.

To sum up, I would prefer in order to depict that without any hesitation, I am in favor in this topic. I ponder that I have illustrated that with the help of this topic emphasize this entire.
