Different paper printability different, packaging printing experts Yihua that description: If you do not, "because material system should" take appropriate technical measures, will give normal production and bring some problems. But even using the same type of paper, due to the differences between different brands or different manufacturers on the paper materials and processes, but also make the quality of the base paper, printability there are some differences. If the white board, white cardboard, glass card belonging acidic, after the printing ink drying more slowly, will lead to semi-finished overprint difficulties nonconforming rate increased significantly; some low-grade paperboard, glass card surface strength is poor, the printing process prone to swap powder, hair loss, and other quality blistering or delamination failure phenomenon.

    Since the printing paper are mostly determined by the customer, so the printing business often in a passive state to accommodate. But even in the face of the paper is less than satisfactory customer selected in order to reduce costs, we have to be carefully designed in the printing process, as far as possible in order to achieve quality improvement. After practice I draw some experience, I would like to share with readers.

- Printing acidic cardboard, it should be fixed fast drying ink.

- For a poor surface strength cardboard, should be adjusted to reduce the viscosity of the ink, while appropriate to reduce printing pressure and printing speed.

- The use of multicolor printing unit and color groups have extra, you can empty out before the color group to be empty imprint to remove paper powder, paper, wool, avoid or reduce the quality failure.

- For India to cover dumb film products, you can not choose too expensive inks, such as high-gloss inks, because the biggest advantage lies in high-gloss ink printing ink gloss, but the product after the matte film coating will cover high ink layer gloss, so will high light ink for coated products will cause waste.

- To pay attention to overprint order process design, such as overprint black or red on a yellow background background character, when the letters or lines, should be printed in black text, letters or lines, and then the yellow or red background background overprint At its top, so both can reflect the advantages of each color, also avoid printing ink by friction damage.
