——STQ-D series polyester ink


The STQ-D series is a medium-gloss, solvent-based ink for the printing of untreated/pretreated PET films. Its application areas include decals and adhesive tape. STQ-D inks provide excellent adhesion, softness, rub resistance and surface hardness. It can withstand the adhesive test of cellophane tape and it can resist oil, alcohol, gasoline and other chemical solvents.

STQ-D ink is suitable for high-speed printing of semi-automatic printers or full-automatic printers. STQ-D inks have a lot of affinity and adhesion to water-based adhesives, as well as to the spraying of most of the varnish (protective oil).

All STQ-D inks, including four-color and other standard colors, whether transparent or highly transparent (opaque) hue, are produced from pigments that are free of lead and other heavy metals and pass the SGS test standard.

Applications Appliques and Tapes

Matrix (substrate)
Polyester film

Mesh meshes In order to achieve maximum color intensity (ie, brightness), it is preferable to use a 100-120T (250-300 mesh) polyester monofilament. For fine detail printing, a 120-140T (300-360 mesh) polyester monofilament is preferred.

Sensitive emulsions All types of oily photosensitive emulsions are suitable (including capillary film).

Ink thinners use STQ-D series inks, which should keep the screen clear and clear to make the printed images clear and vivid (especially the fine details of printing). Depending on the ambient temperature and printing conditions, 15-20% of STQ-D-425 thinner or STQ-D-426 slow-drying diluent can be used. Diluent and ink must be mixed evenly.

The blade uses a polyurethane blade with Shore hardness 70-85. The higher the hardness, the better the effect on the printing of fine details or fine lines.

Ink coverage using 120T (300 mesh) mesh, 70-85 square meters per kilogram of ink

Using a series of inks for drying can keep the screen clear and smooth. The printed pattern is thus clear and vivid (especially the printing of fine details). Drying is particularly important for thoroughly drying the prints and eliminating the residual solvent in the ink layer (large area inked area) of the prints. STQ-D series inks require 30-60 seconds for air drying at 55-65 degrees, and 10-20 minutes for air drying (air drying).

Ink test must be performed before ink test printing:
1. Within 24 hours after the test, it is necessary to test whether the ink is suitable.
2. If the product requires overprinting (such as multi-color overprinting), the ink compatibility with the ink on the substrate should be tested.

——SW-2000 Series Ink


The SW-2000 series is a two-liquid reactive ink. The printing ink film is firm and has high physical resistance and chemical resistance. Widely used in metal, metal painted board, stainless steel, processing polyolefin resin, glass, ceramics and so on.

Applications It is used for many metals such as iron and stainless steel, glass, industrial parts such as metal lacquered plates, signs, and targets, and also for printing on containers and boxes for thermosetting plastics and treated polyolefin resins.

Features high light, strong adhesion, excellent chemical resistance, good wear resistance.

Drying conditions can be natural drying or baking drying, touch drying at room temperature (25 °C) to 5-15 minutes, 24 hours after the complete curing, 48 hours to get the best resistance to performance, but also at a temperature of 60- Drying at -80°C.

Adhesion is superior to other inks in terms of adhesion characteristics, excellent adhesion to metal, metal paint, glass, thermosetting plastics, and treated olefins, but depending on the printed material, Please use it according to the suitability of the purpose.

Please use nylon or polyester 200-350 mesh screen version. The direct plate making method is most suitable.

Mixing ratio and viscosity adjustment SW-2000 series is a set of main agent and hardener. In the use, the required amount of the main agent 4 is mixed with the ratio of the hardener 1 (weight ratio), and after the stirring is uniform, the curing time of 10 minutes elapses, and the viscosity is adjusted to 10% to 10% of the designated diluent for printing. The difference in the weight ratio between the main agent and the hardener occurs with a certain difference in the printed film, so please measure it correctly. The mixed ink must be used within 4 hours.

Wash plate with a special wash net washing network.
