Here are some explanations of terms, which you may not be familiar with:
- Bleed: the part which goes beyond the area defined by the page format. This avoids white "edges" by elements that are printed right up to the edge of the sheet. The bleed is usually 3 mm per side margin.
- CMYK: The four colors (cyan, magenta, yellow and black - CMYK) are also referred to as process colors. Using all combinations of CMYK in 4-color printing you can produce 256 different colors. The range of values of each color goes from 0% to 100%, where 0% corresponds to unprinted and 100% to solid area printing. The four colors are printed on top of each other, all colors SUPERIMPOSED result in BLACK. Industrial color printing with CMYK colors is called Euro scale.
- Grammage: The grammage refers to the density of paper expressed in g / sqm. Normal printer paper has, for example, 80 g / m² (grams per square meter).
- Digital printing: Digital printing is a printing method in which the image is transferred directly from a computer to a printing press. This printing system is usually a photographic printing system such as a laser printer that is designed for long runs. In addition, the printing system may have further devices for cutting, and binding. Unlike, for example, in offset printing digital printing does not need a fixed master (printing form), so that each sheet can be printed differently. This allows inexpensive personalized prints such as bills, credit card statements, bank statements or even advertising specifically tailored to the recipient. Digital printing is more cost effective for small print runs than offset printing.
- DIN-Format: The abbreviation "DIN" means "German industry norm". This specifies the dimensions in which sheets of paper are now mostly traded. The range of formats begins with DIN A0, the largest size in the dimensions 841 x 1189 mm, and continues in halving steps from A1 to A7, which only measures 7.4 by 10.5 cm. Additionally, there are special formats, such as for envelope size designations. The larger the number, the smaller the size. The first number always refers to the width and the second to the height, such as: DIN A4 portrait format: 21 x 29.7 cm, in landscape mode: 29.7 x 21 cm.
- Lamination: By laminating a film is applied to the printed matter. Thus, the printed matter is protected against mechanical abrasion and dirt. The main applications of lamination are covers for books and brochures, packaging and displays.
- Offset printing: By far the most common printing method today. Currently, two-thirds of all the world's printed matter produced by offset printing.
- Pawn: a gaming piece with a wide body and a small 'head'
- Pad printing: Pad printing is an indirect printing method (gravure principle), which has become the most important method for printing on plastic parts which has become indispensable especially in the advertising industry. The pressure plate bears in its surface the to be printed, recessed print image. The doctor floods the color in the recessed print image and takes the excess ink off cleanly. After doctoring an elastic pressure pad is driven over the cliché and takes the remaining ink off with a stroke, to then transfer it to the plastic part, thus printing indirectly. The advantage of this unusual pressure transmission method lies in the deformability of the pad made of silicone rubber, through which the printing of curved surfaces (convex or concave) is readily possible.
- Pixel: both on a screen or printed. In contrast to simple printing point the term "pixel" also implies color depth. A pixel could be seen as three-dimensional and and a printing point as two-dimensional.
- Resolution: DPI (= dots per inch) refers to the number of pixels per inch (2.54 mm). You can also call it pixel density. When used in for devices (e.g.: scanners, printers, screens, imagesetter, etc.) the resolution means the relative density of pixels. For images the relative resolution means the density at which pixels are to be rendered on a device.
- RGB: Red Green Blue, these basic components of colored light form the additive color model. The principle of additive color mixing is that all colors SUPERIMPOSED result in WHITE. Each part can vary between 0% and 100%, so that any color can be achieved. RGB is the color model of the example used in monitors, digital cameras and scanners. For the printing this not being used, as there exists the CMYK model as descirbed above.
- Screen printing: Screen printing is the most famous stencil printing method. With this method almost all materials can be printed. Most banners are labeled in this way. It should be noted that halftones can only be reproduced very badly. Screen printing is a printing method where the printing color is printed with a rubber squeegee to pass through a fine mesh fabric to the printing substrate (paper, plastics, textiles, etc.). At those places on the fabric in the original image in where no color is to be printed, the mesh size of the fabric is made impermeable to ink through a stencil.
