In inkjet printing, multiple pictures are typeset together. The picture is on a white background, and the inkjet cloth is also on a white background. How to make a convenient cutting line for each picture? Large inkjet printer with a width of 3m 10 can actually spray 3m cloth or 3m 1, but the effect is not good, so it is not recommended. Therefore, to make a large-scale inkjet with a width of more than 3m, it is necessary to build seams, so as to ensure the perfection of the picture. The picture can be cut to 3m wide, and the other side can be arbitrary, not exceeding 3 m. I always use light gray lines.
