Some things to pay attention to when processing packaging bags

1. Ink mixing tips

Add ink of what color hue is missing.

The principle of complementary colors should be correctly applied when removing excessive colors from a certain color scheme.

In production practice, sometimes in order to make the white color whiter, a small amount of ultramarine blue (about 1%) is added to the white ink to eliminate the yellow color in the white color.

As long as a small amount of titanium blue is added to the black ink, the yellow tone in the black ink can be eliminated.

When making light colored ink, it is necessary to add color ink to the white ink instead of adding white ink to the color ink. White ink has a strong covering power and adding too much will quickly dilute the color.

When preparing dark ink, it is necessary to add black ink to the ink, and it is not allowed to add color ink to black ink because black ink has a strong coloring power. If you accidentally add too much, you need to add a considerable amount of color ink to adjust the color.

When observing the color sample, try to use a standard light source and use the same base plate.

2. Printing Plate Installation Tips

Check the network cable and layout to ensure that there are no scratches, scratches, or chromium drops. Pay attention to the installation direction and position to ensure that the vertical alignment is basically correct.

Special attention should be paid to checking the cleanliness of the cover and plug during plate installation to prevent assembly errors caused by foreign objects. Be careful when operating to avoid damaging the layout.

Run at low speed and check if the plate roller is eccentric and if there is any rotational imbalance caused by assembly errors.
