Hot stamp Gift Paper Boxes Indispensable accessories for heat transfer industry: glue, ink

As an emerging industry, thermal transfer printing has more and more markets, but it is not so easy to get a share of the pie. How much do you know about the difference between gravure printing, screen printing and color printing? Different types of printing inks and glues need to be used, will you be worried when purchasing? Today, we will answer these questions that users are concerned about, so that you can know more about ink and glue, and avoid you falling into the misunderstanding of purchasing.

1. Gravure printing

Gravure printing is a direct printing method, which directly embosses the ink contained in the gravure pits onto the substrate. Most of the printing of books, periodicals, pictorial, packaging and decoration use gravure printing, but the plate-making cycle is long, the efficiency is expensive, and the cost is high, so it is suitable for mass printing. So what kind of ink is suitable for gravure printing?

1.1LX-402 back coating agent/back coating ink

In the process of product production and printing, this ink can be used to prevent static electricity and prevent the glue layer of the finished product from sticking to the back. Generally, it needs to be coated once with a 200-line coating roller. The coating temperature is generally 80-140 degrees. The cloth speed is 40-80 m/min.

2. Screen printing

Screen printing is through the extrusion of the squeegee, so that the ink is transferred to the substrate through the mesh of the graphic part to form the same graphic as the original. Screen printing equipment is simple, easy to operate, easy to print, plate making, low cost, bright colors, long shelf life, fast delivery and other advantages. So what kind of ink and glue do we need to choose for screen printing?

Let's first understand the basic order of the use of screen printing inks:

Transparent paste→→glitter paste→→white glue→→anti-sublimation paste→→glue

From the basic order, let's analyze ink and glue.

2.1 Transparent paste

Transparent paste: 301 ordinary transparent paste, which is economical, acrylic-grade paint; 305-A4 high-grade elastic transparent paste, which is environmentally friendly, high-elasticity polyurethane-grade paint.

2.2 Glitter paste

BB-030 Glitter paste is highly transparent, used to prepare Glitter.

    2.3 White glue

White glue: 301-B white glue and 304-B high wear-resistant white glue are economical, acrylic-grade coatings; 305-B and 305-AB high-grade elastic white glue are environmentally friendly, high-elasticity polyurethane-grade coatings.

2.4 Anti-sublimation pulp

303-H anti-sublimation glue is used for TC cloth and the barrier of sublimation dyes.

2.5 Hot melt glue

HMA-200A: Economical, suitable for most fabrics. General flexibility.

HMA-529C: Suitable for all fabrics. Elasticity, the best hand feel, and the best washing fastness.

HMA-531A: High elastic polyurethane, special glue for washing water mark.

HMA-533: The elasticity and washing water are OK, but not as good as HMA-529C.

2.6 Screen printing ink

The viscosity of screen printing ink is relatively high, the screen printing is good, the drying is relatively slow, the stirring viscosity is small, and the static viscosity is large. what we produce

Net W-110 transparent, net W-102 white, net W series other color numbers are medium and high-grade products, solvent-based, polyurethane grade, high tensile, high resilience, printed with fine wash water marks, and can not be ironed by high temperature. Variation, can be used for heat transfer production of washing water mark or other medium and high-end screen printing, the product has passed the SGS EU environmental protection standard; PA-102PVC white joint ink is specially used for heat transfer production of PVC sheet, no elasticity, but good hiding. , High adhesion products have passed SGS EU environmental protection standards.

3. Color printing

Color printing is a direct or indirect method to make an image or text original as a printing plate, apply color ink on the plate, and transfer the color ink to paper or other substrates under pressure, which can achieve saturated and bright colors. , wide color gamut, good transition, far more than the traditional printing effect.

After understanding the glue and ink that gravure printing and screen printing need to use, what do you need for color printing?

Color printing ink is divided into: sublimation color printing ink, UV color printing ink, low temperature color printing ink, high temperature color printing ink.

3.1 Sublimation Color Printing Ink

It is an imported disperse dye with good transfer rate and bright color, which is used for offset color printing.

3.2UV color printing ink

Tough UV ink, used for heat transfer color printing, bright color, alkali-resistant and wear-resistant color layer; can also be used to print soft PVC materials.

3.3 Low temperature color printing ink

It is suitable for color printing of low temperature heat transfer. 302-B red is a special customized product, which is resistant to sunlight and washing.

3.4 High temperature color printing ink

Suitable for high temperature heat transfer color printing

For example, what are the precautions for heat transfer with gradient colors?

If you want to do gradient heat transfer, you must do color printing; pay attention to the effect of gradient color, because it is color printing, gold, silver and other metallic colors or brighter colors cannot be done, these colors must be done by screen printing. OK.
