[China Packaging News] as an emerging industry, heat transfer printing has more and more markets, but it is not so easy to get a share. How much do you know about the difference between gravure printing, printing and color printing? Different kinds of printing inks and gums need to be used. Will you worry when choosing? Today, we will answer these questions for you one by one, so that you can better understand the ink and glue, and avoid you from falling into the misunderstanding of purchase

1. Gravure printing

gravure printing is a direct printing method, which directly imprints the ink contained in the gravure pit on the substrate. The gravure printing text has a convex feeling, rich levels, clear lines and high quality. Intaglio printing is mostly used in the printing of books, pictorials, packaging and decoration, 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

this kind of ink can play an anti-static role in the process of product production and printing and prevent the adhesion between the finished glue layer and the back. Generally, it needs to be coated once with a 200 line coating roller, the coating temperature is generally degrees, and the coating speed is meters/minute

2. Printing and printing

printing and printing is to make the ink transfer to the substrate through the hole of the image and text part through the extrusion of the scraper, forming the same image and text as the original. It has the advantages of simple printing equipment, convenient operation, simple printing and plate making, low cost, bright colors, long storage life, fast delivery, etc. So what kind of ink and glue do we need to choose for printing

let's first understand the basic order of printing ink use:

transparent paste, golden onion paste, white glue, anti sublimation paste, glue

from the basic order, let's analyze the ink and glue

2.1 transparent paste

transparent paste: 301 ordinary transparent paste, which is an economical, acrylic grade coating; 305-a4 advanced elastic transparent paste is an environmental friendly, high elastic polyurethane grade coating

2.2 golden onion paste

bb-030 golden onion paste is highly transparent and is used to prepare golden onions

2.3 white mastic

white mastic: 301-b white mastic and 304-b high wear-resistant white mastic are economical, acrylic grade coatings; 305-b and 305-ab advanced elastic white glue pastes are environmental friendly, high elastic polyurethane grade coatings

2.4 anti sublimation paste

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. Solvay TORLON and spire super performance polymers used in these fields also have more advantages, with general elasticity

hma-529c: suitable for all fabrics. It is elastic, feels best, and has the best washing fastness

hma-531a: high elastic polyurethane, special glue for washing marks

hma-533: elasticity and washing water are OK, but not as good as hma-529c

2.6 printing ink

printing ink has relatively high viscosity, over printing, relatively slow drying, low stirring viscosity, and high static viscosity. The

w-110 transparent, w-102 white, other color numbers of W series, are medium and high-end products, which have been solvent type, polyurethane grade, high tensile, high rebound, printing fine washing marks. After high temperature pressing, they can be used for washing marks or other hot stamping production of medium and high-end printing. The products have passed SGS EU environmental protection standards; Pa-102pvc white joint ink is specially used for hot stamping production of PVC sheets. It is inelastic, but has good covering property and high adhesion. The product has passed SGS EU environmental protection standards

3. Color printing

color printing is to use direct or indirect methods to make an image or text original into a printing plate, apply pigment printing ink on the plate, and transfer the pigment printing ink to paper or other substrate under pressure. It can achieve color saturation and gorgeous, wide color gamut, and good transition, which is far more than the traditional printing effect

after knowing the glue and ink needed for gravure printing and printing, what kind of color printing needs

color printing inks are divided into sublimation color printing inks, UV color printing inks, low-temperature color printing inks, and high-temperature color printing inks

3.1 sublimation color printing ink

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, which is guaranteed to be replaced in hot stamping color printing within 15 working days, has bright color, and the color layer is alkali resistant and wear-resistant; It can also be used for printing soft PVC materials

3.3 low temperature color printing ink

is suitable for color printing of low temperature hot stamping. 302-b red is a special customized product, which is sun resistant and washable

3.4 high temperature color printing ink

suitable for high temperature hot stamping color printing

for example, what are the precautions for gradient hot stamping

if you want to do gradient hot stamping, 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 colors that are more colorful cannot be made. These colors must be printed
