Hao Qian teaches you how to solve the problem of bottom film residue on acrylic display screen printing?

We do n’t need to introduce the editors. We also know how to use acrylic display stands. Almost all of our days can be seen with acrylic display stands. However, during the screen printing of acrylic display stands, there will be a problem of residual film. How to solve the problem? Hao Qian will introduce it to you.

The reasons and solutions for the residual film on the acrylic display shelf during screen printing:

        1. Uneven coating: At this moment, wire mesh tension can be added to apply glue evenly with a screen pulper.

        2. Improper selection of exposure light source: conduct an exposure test and adjust the exposure time.

        3. It takes a long time to prepare and use the photosensitive emulsion: choose the light source reasonably, and the strong ultraviolet light (halogen lamp) is suitable.

        4. When the printing plate is printed, the bottom plate and the film are not touched properly, and the bottom plate is of low contrast: check the transparency and blackness of the bottom plate.

        5. Thermal crosslinking caused by excessively high drying temperature: Control the drying temperature according to the instructions of the photosensitive adhesive.

        6. When the printing plate is printed, the bottom plate and the film are not touching properly: use vacuum adsorption or other methods to make it tightly connected.

        7. Lack of exposure or overexposure: shorten the period of use.

        8. The timing, method and strength of printing are not correct: the timing, method and strength of printing are controlled correctly.

        9. Lack of development time: add graphics to show development time.

The above 9 points are about the causes and solutions of the acrylic film display screen showing the residual film during the screen printing process. If we encounter similar problems, we can use the corresponding solutions and hope to assist us.
