Four boot printing small business card - to subtotal subtotal

Frequently encountered in the daily production of single-format printing 50mm × 90mm size small business card printing. In the past, this type of "mini-print" has always been printed on small disc printers, which have been eliminated with the development of the times. Under this circumstance, starting from the actual situation, the DT400 type quad open relief automatic platform printing machine with the minimum printing width of 130mm×165mm was slightly applied to the “flexibility” subtotal, ie breaking the convention and achieving a small business card printing size of 50mm×90mm. The printing can be used to its full potential to maximize the potential of the equipment.

The specific approach is:

1. Identification and addition of print positioning (regulations). The positioning of the paper edge of the machine (ie, the front gauge) is achieved by three sets of forward gauge devices located on the drum. These three sets of front gauge spacing are somewhat different to accommodate the requirements of different printing web positioning. The distance between a pair of front gauges is exactly within 90mm, and it is suitable to use the long edge of a small business card as a fistula, and the short side of 50mm is used as a sidebar edge. However, the side gauge device on the machine is 100mm away from the front gauge line of the drum and apparently cannot be used. Based on this situation, we stuck a piece of "-" paper folded with a white paper with a width of 10mm and a length of about 80mm on the appropriate part of the paper feeding table (about 30mm from the front gauge) as the positioning point on the side of the card. Make sure that the side of the business card is positioned correctly.

2. Remove the rocker arm and manually position the paper. Since the size of business card paper is too small to achieve automatic paper feed, it is necessary to remove the rocker arm from the machine to remove the mechanical obstacles to the manual paper feed, so that manual paper placement can be more flexible. Each time the paper is fed, the rocker arm should be moved to the deflation work point, and then the business card paper should be placed in the paper feed table to be positioned. Then the 揿 button should be pressed to allow the drum to rotate for one week to achieve imprinting.

The use of DT400 type four open relief automatic platform printing machine for printing small business cards, using manual paper although the production efficiency is not as high as automatic paper, but for small quantities of business card printing is still more suitable, its plate making, printing is convenient, and the printing quality is excellent On the disc printer. With a business card printed with a resin plate, the print quality can also be comparable to offset printing products. "Small machine printing" seems worth it.
