What should I do if the screen printing ink dries slowly, and what is the reason why the printing in

Is it slow to dry when printed onto the product? Or is the ink itself slow to dry?

First, replace the diluent with a slightly quicker diluent.

Second, replace the ink, you can use a quick-drying ink.

Third, add a blowing device to improve the drying speed of the surface of the finished product.

Fourth, increase the ambient temperature and increase air circulation. This can also appropriately increase the drying speed of some inks.

Fifth, increase auxiliary equipment, ceramic infrared drying line.

The above basically contains the basic solution to this problem, if not, it needs to be adapted to local conditions, and the specific analysis is solved! After all, you didn't mention what needs to be printed? What kind of requirements? Your production environment, the added value of your products, and more!

Hello Kiss is happy to answer this question for you. What are the reasons why the printing ink does not dry, and the reasons are as follows: The amount of ink supplied is too large. The amount of ink supplied is too large, resulting in the ink layer is too thick, and the UV lamp can not dry the ink in time, which mainly occurs when printing the field work.

In this case, the amount of ink can be reduced as much as possible without affecting the quality of the printing bucket. If you can't achieve good results, you can consider moving the field to the first few groups of printing units, so that after the baking of multiple UV lamps, the failure will be reduced. The power of the UV lamp is not enough.

The power of the UV lamp is not enough due to the aging of the UV lamp or other reasons, which will also cause the ink to not dry. In this regard, adjust the power of the UV lamp to the maximum gear, if it is not dry, it can be solved by changing the UV lamp. Early selling silver was printed too fast.

Printing too fast will cause the UV lamp to have no time to dry the ink. This can be solved by changing the printing unit or reducing the printing speed. When printing field jobs, the printing speed should be kept at about 20min.

1. It can be heated and dried, which will make the ink dry quickly;

2. Add Bixiao fast drying dissolution and repentant agent to the ink, such as acetone butanone dismantling, etc.;

3. You can try to print some books;

4. You can use a screen with smaller mesh;

5. Put it in a ventilated place, or you can use a fan to blow on the ink, which can speed up the drying speed.

To make the screen printing ink not bright, you can take the following measures to disturb the transportation land:

Make sure the ink is of good quality. If the ink is too flat or too dense, it will cause the varnish to not shine and not highlight enough. The solution is to choose high-quality inks and choose the right quality and color according to actual needs.

Make sure that the pressure of the scraper is appropriate. The squeegee is a very important part of silk screen printing, it needs enough pressure to push the ink smoothly during printing. If the squeegee pressure is insufficient, it will cause the ink concentration to be uneven and eventually lead to the silk screen printing varnish not shining.

The best solution is to check the pressure of the scraper and adjust it in time.

Determine the amount of gap between the screen print and the substrate.

The main basis is:

The size of the screen printing plate size. The amount of tension in the net. The center sag of a screen printing plate. The shape of the substrate. The nature of the material of the substrate. Surface morphology of the substrate. ink viscosity, etc.

The gap between the screen printing plate and the substrate has different clearance values due to different printing conditions. Generally, the surface of ceramics, glass, metal surfaces, hard plastics and other substrates with low ink absorption has higher requirements for printing gap value. However, the requirements for the printing gap value are not so strict for objects with soft surfaces such as cloth, paper and soft plastics with large ink absorption.

In general, prints that require high precision require a gap value between 1-3 mm when printing. For ordinary prints, the gap can be 2-6 mm. The gap value is smaller when printing on a curved surface, while the gap value is larger when printing on a flat surface.

2.In general, the following measures can be taken to prevent bubbles from forming in the ink layer. Use hydrophobic solvents whenever possible.

When bubbles are generated in the ink itself, an appropriate amount of defoamer can be added to the ink. If the ink fluidity is poor, when the screen printing plate is lifted, the ink flow is relatively small, and the screen traces cannot be filled, and the surface is smooth and flat grinding layer cannot be obtained.

3.In order to prevent the appearance of screen marks after printing, the following methods can be used.

Printing is carried out with a more fluid ink. Consider printing with inks that dry slowly to increase the flow time of the ink and allow the ink to cure gradually. Try to use a single-diameter screen with a thinner wire diameter when making plates.

Check whether your air conditioner air vent is blowing in the direction of the screen plate, check the temperature and humidity, I don't know which ink you use? It is best to measure the viscosity of the ink with a viscometer.

I am a plastic bucket manufacturer. Some customers also need to print, the weather is too hot, the ink dries too fast to print, too thin, a little dry, it dries quickly! I'm scared!

I looked on the Internet and found that there is a kind of water called slow dry water, which is used for screen printing. ** 1kg in 40 pieces. I bought it back and used it for a while, and the effect was quite good.

You can try!

What is the reason for the uneven ink in the screen printing process?

As far as inks are concerned1If the ink is not selected properly, the ink should be replaced; 2.The ink dries too quickly, so choose a slow-drying ink; 3.

If the ink viscosity is too high, choose a low-viscosity ink. Or the ink is poorly blended, and the noisy or normally mixed ink is mixed into the ink skin, and when printing, due to the effect of the solvent, it swells and softens, and the mesh that should be returned to the ink is blocked, which plays the role of the plate film, so that the ink cannot pass through.
