Question about bag making and use of packaging bags

In the process of designing and making packaging bags,attention should be paid to the operability problems in the process of bag making and slitting.Some art designers did not consider the errors in the process of bag making and slitting.To difficult.

The surrounding color of the composite bag should be designed to be similar or the same color.If the color contrast between the top,bottom,left and right of the packaging bag or roll material is large,there will be obvious contrast between the vertical and horizontal layouts.Since the bag making machine,slitting machine and automatic packaging machine cannot cut or cut absolutely accurately,they generally have a deviation of more than 1mm,so the bag made or the roll film that is cut out will be at the cutting place.A line with a large contrast,which affects the appearance.

Human eyes are recognized by the contrast between the text pattern and the background color.Therefore,when designing,you should fully consider whether the contrast between the color is strong.Avoid using similar colors,otherwise the small contrast will easily cause ambiguity.If there is no background color,and the text pattern is small or its color is lighter,generally is cannot be combined with the glossy surface of aluminum coating film or pure aluminum foil.Otherwise,it is difficult to recognize the text pattern due to the flash of the aluminum film or aluminum foil glossy surface.
