Now, offset speed quickly, high speed machines, and its printing pressure must be increased accordingly, the reason is: (1) to increase the paper printing pressure powerless compensate for the short time brought imprint blots not strong, emptiness drawbacks to improve the robustness of imprinting. (2) Machine speed continuously improve Hamburg greaseproof paper, the drum roll with increasing radius must also be reduced utilization factor. Roller diameter unskilled laborer, compression width in the rolling process is reduced accordingly greaseproof paper prices, the compression width in the rolling process is reduced accordingly, if the pressure does not increase sales of coated paper bags printed greaseproof paper, will also affect the transfer of anti-oil layer thickness of the ink bag is attached to the surface of the paper refers to the average thickness of the ink layer in the vertical direction on the paper. Whether just the right ink film thickness, which is the best printing color levels to restore critical factor. Ink sheet is too thin, ink is not uniformly coated paper covering the paper, prints dull, increasingly shallow color, fuzzy hierarchy; ink layer is too thick, solid density on the sheet reaches the maximum field density of the ink, Quality is not only not improved, but caused serious outlets increases, causing paste version or grade level and other printing fault, prints darkened area outlets vague dull level. Because of the complexity and variability of inks, printing conditions, substrate conditions, leading to uncertainty and ink film thickness non-uniformity.
