The type of printing patterns and common printing problems

1.Bullet pattern
What are the common patterns you make? What I often do is the grey cloth pattern, grey cloth positioning and cutting printing. Do you know the difference? Grey cloth printing is circular, direct spread paper sample can be cut, the flower is circular, each piece of the flower position can not be exactly the same, big goods or processing. As long as we do a good job of small circulation, do a good job of one to one document, large goods general printing factory can help to deal with.

Positioning printing
I've done it on cut slices. This is to understand the shrinkage rate?
The requirements of positioning printing will be relatively high, directly according to the wheat paper sample to determine the location of printing. Usually use the row of wheat paper to row the grey cloth pattern, and then the back bed will take the paper to set the position a cut. Just is the position, is the position of the pattern, the beginning of the sample master will be the shrinkage rate. The MSGM has a suit with a white bottom and a black top, which is a positioning print.

Problems easily encountered during the grey cloth printing period:

One of the problems I encountered this year was manual dyeing, and the defective rate was extraordinary, and because the production department did not follow the designer on the prenatal samples, and the later ones were all problems. The later solution was to replace the dye pattern with a print, and a cut print. The cost has increased, but the defective rate is guaranteed. It's hard to feel different from the original one. Some clothes may not be dry, the workers will fold up, and repeatedly stained dirty. This lesson is to beware of factory owners some want to do business disorderly orders, the risk or their own control. At the same time, some basic printing techniques can replace the uncontrollable manual dyeing.The quality requirements of the mortar can not fall off, can not be warped, fall off, uneven. Use your finger to poke, if off, the quality is not good. The seal can not penetrate the bottom, can not show the sand bottom and red phenomenon. Silver to hot evenly, not disconnected, or wrinkled into a ball. In addition, the printing is high temperature. In the printing process, if the control is not good, there will also be yellow phenomenon, which belongs to the improper operation of the printing factory. There is also the rubber paste printed in the elastic fabric, easy to fall off the phenomenon.
I made a fall off, are in the copy of the material to solve. On the front page, send the water, wash, pass the water, fall off. Because if the water is printed, customers buy the water will also have a problem. Generally is after printing water, washing should be printed after washing.
As I mentioned above, MSGM has a white hem and the other black prints. We made a similar direction. As a result, the white part is too easy to be contaminated with black ink, which cannot be solved by four or five factories. If the difference between the two colors is too big, the light part is easy to be contaminated with dark dye. So at the beginning of the version to consider this problem, try not to color too much. The printing factory machines have been dismantled and washed, but they can only be improved, no way to completely eliminate, there will be a little. We dye in human silk color fastness is not good is also common, reactive dye, color fastness is better.
I see some fabric chamber of commerce in the color card to provide several active dyeing fabrics, said it can be splicing, other dark.
In the process of playing the version will often encounter the wrong color. How do you try to avoid it? Is the early communication work as far as possible?
It's usually replayed. For example, if the pattern is deep, then we will adjust the color of the picture slightly lighter.
