Printing Terminology 1

1. Direct printing: refers to printing directly through a digital printing machine.

This printing method can directly input and print various high-quality printed materials from a computer, saving a lot of time in traditional printing.

2. Print-out: refer to computer manuscripts that can be directly printed.

3. Sample: Samples will be made before formal printing. The samples can allow customers to visually see the appearance of the finished product, which is convenient for checking and verification.

4. Resolution: A term used to describe the level of finesse, common in graphic design are display resolution DPI and image resolution PPI.

DPI dot density: refers to the number of dots per inch area, which is the standard for measuring the fineness of printed images. The higher the value, the higher the fineness of the picture.

PPI pixel density: refers to the number of pixels per inch area, which is a standard for measuring the level of realistic restoration of the display screen. The higher the value, the more details of the picture.

5. Bleeding: In order to ensure the finished product is neat and uniform, all the printed matter will be cut uniformly.

If you do not leave a more generous printing position on the edge, the printed matter will have white edges, which makes people feel that the printing quality is low, so you need to leave room for the printed matter. The printing position is for cutting off, and the left position is the bleed position. Bleeding is usually set at 3mm.

6. Overprint Imprint: one color over another. Because the color of the ink will affect each other, the original color will change after overprinting.

7. Trapping In order to avoid the color change caused by overprinting, the overlapping part of the two colors is usually hollowed out so that the respective colors can be displayed accurately, but because the actual printed color plates are difficult to be perfectly aligned, it is easy to leave a blank space, so the color of the upper or lower layer will be appropriately expanded according to the degree of depth to ensure that the printed product will not leak white.
