Composite packaging bag and use question, did you shot?

Composite bags should be paid attention to in the process of design and manufacture in the bag and the practical problems in the process of cutting, some graphic designer did not consider in the process of bag making and cutting error, and make the bag and points to meet with difficulties. Composite bags should be designed around for similar or the same color, if the packaging or packaging coil up and down or so the color contrast is bigger, after the vertical and horizontal layout, puzzle will have obvious contrast. Because the bag making machine, cutting machine and automatic packing machine for cutting or cutting can't absolutely accurate, generally have more than 1 mm deviation, thus making the packing bag of bags or cutting out of packaging film in cutting place there will be a difference between lines, so as to affect beautiful. The human eye is by the text background color and contrast to identify, therefore, when the design should be considered whether the text background color of color and contrast strongly, avoid by all means use similar color, or contrast small cause blurred. Without the base, and smaller text or its color is light, and generally cannot smooth composite aluminum plating film or pure aluminum foil, or as a result of the aluminum plating film or aluminium foil smooth ShanYan, makes the text pattern is difficult to identify.
