Bleed/Trim:
Bleed is a printing term that is used to describe a document which has images or elements that touch the edge of the page, extending beyond the trim edge and leaving no white margin. When a document has bleed, it must be printed on a larger sheet of paper and then trimed down.
CMYK
CMYK stands for cyan, magenta, yellow and key(black) and is the color profile used in print. CMYK color is created using a subtractive process. This means that each additional color means more light is removed to create it. When C, M, and Y are combined, you will not achieve pure black, but rather a dark brown color. K is used to completely remove the light from the printed picture, which the eye sees as black.
Corporate Design
A corporate design is the official graphical design of the logo and name of a company or institution used on letterheads, envelopes, forms, folders, brochures, etc. The house style is created in such a way that all the elements are arranged in a distinctive design and pattern. This includes dictating what ink pantones should be used in the coloring, and what typefaces. Governments may have corporate designs as well. On June 2, 1999, the German federal cabinet introduced a corporate design for the flag of Germany. The term ‘corporate design’ is not the name of a specific design profession. Corporations do have special design needs based on their behaviors. They communicate their mission, objectives, needs, and product information — with users, clients, or members; with suppliers, distributors, service providers; with the surrounding community and the media; with financial institutions and other corporations, and with the state. They create, acquire, modify, organize and distribute large amounts of information and raw data, as well as goods and services.
Crop Marks
Crop marks, also known as trim marks, are lines printed in the corners of your publication’s sheet or sheets of paper to show the printer where to trim the paper. They are used by commercial printers for creating bleeds where an image or color on the page needs to extend all the way to the edge of the paper.
DIN format
DIN is an abbreviation of “Deutsches Institut für Normung“ (German Institute for Standardization). The format specification is generally in Width x Height so you know if its portrait or landscape. Here a few DIN formats from A0 to A8:
DIN A0 = 841 mm x1189 mm
DIN A1 = 594 mm x 841 mm
DIN A2 = 420 mm x 594 mm
DIN A3 = 297 mm x 420 mm
DIN A4 = 210 mm x 297 mm
DIN A5 = 148 mm x 210 mm
DIN A6 = 105 mm x 148 mm
DIN A7 = 74 mm x 105 mm
DIN A8 = 52 mm x 74 mm
EPS
EPS is a file extension for a graphics file format used in vector-based images in Adobe Illustrator. EPS stands for Encapsulated PostScript. An EPS file can contain text as well as graphics. It also usually contains a bit map version of the image for simpler viewing rather than the vector instructions to draw the image.
Grammage
The mass per area of paper measured in grams per square meter (g/m²).
Offset printing
Offset printing, also called offset lithography, is a method of mass-production printing in which the images on metal plates are transferred (offset) to rubber blankets or rollers and then to the print media. The print media, usually paper, does not come into direct contact with the metal plates. This prolongs the life of the plates. In addition, the flexible rubber conforms readily to the print media surface, allowing the process to be used effectively on rough-surfaced media such as canvas, cloth or wood. The main advantage of offset printing is its high and consistent image quality. The process can be used for small, medium or high-volume jobs.
Pdf stands for Portable Document Format. It is a file format used to present and exchange documents reliably, independent of software, hardware, or operating system. Invented by Adobe, PDF is now an open standard maintained by the International Organization for Standardization (ISO). PDFs can contain links and buttons, form fields, audio, video, and business logic. They can also be signed electronically and are easily viewed using free Acrobat Reader DC software.
Proof Print
A proof is a preliminary version of a printed piece. It provides a close representation of how the piece will appear when printed. Proofs are created to ensure that the client and printer are in complete agreement on the desired outcome before going to press.
Resolution of pictures
For professional printing we will need at least 300dpi(dots per inch) in full-tone and half-tone separations, and at least 600dpi for Line-art. If the pictures need to be enlarged the resolution has to be even higher.
RGB
The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. The main purpose of the RGB color model is for the sensing, representation and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography.
