There are many noteworthy details in the pre-press design process of flexible packaging. Here, we will discuss with you the details of minor text and line design considerations.
(1) Small text and lines should be designed as a single package to avoid inaccurate multicolor printing. The width of the thin line must not be less than 0.1mm, otherwise it is easy to lose or unclear in the printing. The net height of the Chinese font is not less than 1.8mm, and the net height of the English font is not less than 1.5mm.
(2) Anti-white text should pay special attention to the design, if the text is small, especially when the stroke is small, use a single color. The choice of font should also be noted that round body, black body, and isotonic body are the better choices, and fonts with different strokes, such as Song and Old Times (thick and vertical), should be used with caution when designing. With this type of font, it is important to note that the net height of Chinese fonts is not less than 2.5 mm, and the net height of English fonts is not less than 2 mm. Warm printing
Poor print overprinting 2006-09-19 09:05 Phenomenon: Wet inks printed on the back during wet overprinting cannot be successfully attached to the previously printed inks.
the reason:
(1) The viscosity of the ink after printing is too high compared to the ink printed beforehand.
(2) The first Printing Ink is slow and has a large amount of ink.
(3) The color intensity balance of the four-color ink is not appropriate.
Approach:
(1) Printing with high viscosity inks first, printing with low viscosity inks, and the ideal stickiness requirement should be gradually reduced in the order of overprinting colors.
(2) Fast and fast ink printing is used, and the high density is printed thinly. The pattern area is small and printed beforehand to facilitate the overprinting.
(3) The color intensity of any set of wet multi-color overprint inks is balanced. When overprinting, the same amount of ink can be used. If not using the same set of inks together, it should be handled properly.
