Yes, I threw a lot of information at you today. But it isn’t that hard to remember. I’m going to do several/multiple posts to cover what I talked about.
Software: What we are starting with.
- InDesign: Asset Management software – where the designs and assets from Photoshop and Illustrator are assembled. Essentially the digital drafting table where production art is assembled.
- Photoshop: Image Editor – photography processing, illustration and graphics creation – Raster-based (Pixels).
- Illustrator: Graphics Creation – logos, illustrations and graphics – Vector based (math-based).
Offset Lithography – big commercial printing companies. Big offset lithography presses can either print ink or not print ink. They do not print tonal ranges of the ink. 100% ink or 0% ink on paper. Two types of ink used in Offset Lithography – Process Inks = Cyan, Magenta, Yellow and Black (CMYK) and Spot Color Inks (Pantone Matching System – PMS) Spot color inks are physically mixed inks while Process (CMYK) inks are a visually mixed illusion of different colors and tonal ranges. Process inks are transparent and Spot color inks are typically opaque. Both process inks and spot color inks are subtractive color modes. Subtract from 100% to 0% of the four colors to get to white. To create the illusion of tonal range and full-color a mechanical conversion must take place in continuous-tone images (Photography and artwork). The images are converted into tiny little dots – a series of dots. These little dots are called Benday dots which allows for presses to reproduce images. When a black and white photograph is converted to a series of little dots it is called a Halftone. When a color image is converted and separated into four sets of colors (CMYK) of little dots they are called Separations. Still with me? I am trying to keep this a simple as possible. Don’t let eyes glaze. Pay attention here.
Web-based publishing – Color modes used on the web are RGB (Red, Green Blue) and is an additive color process – Add from 0 to 255 (all three colors) to get to white.
…more to come. Stay tuned.
