1) The difference between vector and raster graphics is that raster graphics are composed of pixels, while vector graphics are composed of paths. A raster image shouldn’t be stretched so much because you will be able to see the pixilation depending how good the quality the file is. A vector image can be stretched as much as you want due to the composed path and math algorithms that make up the files size.
2) Printing an image at a resolution of 300 pixels/inch squeezes the pixels in close enough together to keep everything looking sharp. So the resolution of a printed piece should be 300. The resolution of a digital media file should be (for example a digital painting) should be 300 dpi OR 150-200 depending how big the file canvas is the artist is using. Resolution knowledge is important because if you us too low of resolution on a printed piece it will look fuzzy and pixelated. While using too high of a media file could cause slow issues with a website or loading the artwork and detail.
3) Pantone colors are colors made by a specific business (Pantone) but are used by designers everywhere as a basis for digital color swatches and identification of shades. CMYK, also known as the four-color process, stands for the colors used in the printing color process: cyan, magenta, yellow, and black. This printing color process is generally used in inkjet printers while Pantone Color is color specific and takes highly precise mixes of ink to create an exact color. It uses pre-determined colors to “match” a certain color used in the design process. Thus, it’s known as the Pantone Matching System.
4) Preflight analysis for print and web: task of checking a computer graphic doc in preparation for the manufacturing process
5) Font Management / Adobe type 1 fonts with TrueType Adobe Type 1- by Adobe. PostScript font- allows for high res resizable graphics, vector based. TrueType- by Apple- contain both the screen and printer font data in a single component, making the fonts easier to install.
-Describe six pre-imaging file analysis processes that should be considered when developing a computer graphic for reproduction manufacture.
Raster image processing (RIP) technologies
Color Management Trapping to lithographic and flexographic specifications
Transparency
Imposition for pre-RIP and post RIP for media utilization
Preflight analysis and automation for computer file creation
-Describe four major imaging technologies that utilize computer graphics to image on different substrates.
Electrophotography- (toner based digital printers)
Lithography
Inkjet
Flexography
-How many addressable values can be recorded in an eight-bit byte of computer data?
256 glyphs
-WYSIWYG is an acronym for What You See Is What You Get. WYSIWYG is a way of designing electronic documents so that content such as text and graphics is displayed on screen during editing in a way that corresponds exactly to its appearance when printed or displayed as a finished product.
-How many kerning pairs are present in a ‘good’ font file?
600-800 kerning pairs
-What color matching library has been developed exclusively for process colour printing inks (CMYK)?
PANTONE
-What two printing processes must have trapping applied to computer graphics files before making printing plates?
Lithography and Flexography
-What can a page layout artist do to a graphics file if the transparent elements on the page are dropping out or not processing in the RIP?
The artist could work with multiple layers and try different ways to have each element transfer with multiple number layers, or rasterize the art itself
