Paper on Chapter 11 Paper on Chapter 11 Section 11 Setting up a Document for Prepress and Printing Goals Investigate shading hypothesis and goals issues Work in CMYK mode Determine spot hues Make crop marks Make drains Spare document as a PDF Investigate Color Theory and Goals Issues Vitality from the sun hits the earth in waves: X-beams Gamma beams Bright beams Visual light beams (white light) Investigate Color Theory and Goals Issues White light separated into seven particular hues (as found in a rainbow) Red Orange Yellow Green Blue Indigo Violet Investigate Color Theory and Goals Issues Hues in obvious range can be broken into red, green, and blue (essential hues). †Primary hues can't be decreased †Additive alludes to the way that the essential hues consolidate to deliver different hues †Red, green, and blue, when consolidated similarly, produce white light †True dark is the nonattendance of all light Investigate Color Theory and Goals Issues White light Investigate Color Theory and Goals Issues Subtractive essential hues Three things can happen when light strikes an item: †Reflection †when light ‘bounces’ off the item †Absorption †when light isn't reflected †Transmission †when light goes through an item Investigate Color Theory and Goals Issues Contingent upon physical properties of item, fluctuating measures of light are reflected, retained, and transmitted. Red, green, and blue light not reflected in equivalent sums. Shading depends on rates of red, green, and blue reflected, and the shading that mix of light delivers. Investigate Color Theory and Goals Issues Investigate Color Theory and Goals Issues Cyan, red, and yellow are called subtractive essential hues. Each is delivered by expelling or taking away one of the essential hues totally. Covering every one of the three shades would ingest all hues. Investigate Color Theory and Goals Issues Cyan is â€Å"minus red† Red is â€Å"minus green† Yellow is â€Å"minus blue† Investigate Color Theory and Goals Issues Shading printing utilizes the three subtractive essential hues in addition to dark to deliver a shading picture or tint. The standard shading for paper is white. Cyan, red, and yellow are made to be straightforward. The shading you see on a printed page is light reflected off the page. Investigate Color Theory and Goals Issues The shade of the printed picture is reflected off the paper, not the inks Investigate Color Theory and Goals Issues CMYK inks (process inks) are not great. Capacity to transmit light not great. In principle, covering every one of the three inks should create dark on the grounds that no light would be reflected. Investigate Color Theory and Goals Issues The picture on the left was printed with just CMY inks Dark inks add difference and profundity to picture on the picture on the privilege Investigate Color Theory and Goals Issues Artist is a vector-based drawing program. Designs you make are called vector illustrations. Vector illustrations are goals autonomous on the grounds that they are not included pixels. You can resize vector illustrations with no worry for quality. Investigate Color Theory and Goals Issues You can change over vector designs to bitmap illustrations by a procedure called rasterization. Bitmaps are involved a rectangular lattice of hued squares called pixels. Pixels is short for picture components. Investigate Color Theory and Goals Issues Pictures made out of pixels include: Scanned pictures Computerized pictures Rasterized Illustrator designs Investigate Color Theory and Goals Issues The quantity of pixels in a given inch is alluded to as the image’s goals. To be compelling they should make the figment of ceaseless tone. Investigate Color Theory and Goals Issues Compelling goals alludes to the goals of a set picture dependent on its size in the design. Pertinent just to bitmap illustrations since vector designs don't have pixels. Investigate Color Theory and Goals
