Digital cotton direct injection printing classification

One,Cotton direct injectionPrinting can be divided into digital thermal transfer printing (printed on paper by digital machine and then transferred to cloth) and pure cotton direct-injection digital printing.

After the customer provides the pattern, there is no need to separate the colors. The color is directly printed according to the customer's requirements, the pattern is trimmed, printed on the paper by a digital printer, and then transferred to the fabric through high temperature (generally 200-230 degrees) and high pressure.

Ink used: dispersion ink

Fabric requirements:

1. It is best to be white or light-colored (the printed type must be darker than the gray fabric)

2. The composition of the fabric must be high temperature resistant. Generally, all polyester or polyester content is relatively high, such as (80/20 polyester cotton, 95/5 polyester polyurethane

3. Do not add silicone oil to the grey fabric before printing. The setting temperature is slightly higher, and the shrinkage of the fabric after printing will be smaller.

4 Do not add fluorescent agent, if it is absolutely necessary, add as little as possible

The garment printing machine printing is aimed at cotton, real silk, rayon, linen or cotton polyester, cotton and ammonia with high content of cotton, and there is no need for color separation. Retouching and color printing are required.

Ink used: special ink

Fabric requirements: 1. It is best to be white (or natural white) cooked blank, or light-colored (the printed type must be darker than the color of the gray fabric), cotton fabrics need to be singed

2. The grey fabric must be sizing before printing, in order to ensure the stiffness and chromaticity of the grey fabric

The advantages of digital printing: fast sample production, no plate making, good environment, fast digital sample production, no color separation for any pattern, high precision, bright colors, strong layering, can achieve photo effects, suitable for small batch orders

Disadvantages: high cost, not suitable for large-volume orders, complicated cotton process, and difficult to control shrinkage

2. The ink and fabric requirements for the thermal transfer printing of the treadmill printing machine plate are the same as the digital thermal transfer printing. The paper includes white paper, yellow paper, and newsprint, which are thinner than digital thermal transfer paper.

Advantages: low unit price, suitable for mass production, bright colors, rich layers

Disadvantages: only suitable for patterns that can be color-separated, color-separated drawing, high plate cost, printing color is not easy to control, there are errors, the first plate is printed, the production cycle is longer, and the production environment is poor.
