Check junkpile exercise.
Work individually with students on Logo project for half of class . If you are DONE with your logo project, then choose one exercise out of CIAB that we haven't done and do it. You will get extra credit for this
Document Color Mode
Review where to pick
colors: Tool palette, Color Palette, Swatches Palette
Wheel (do in AI on screen).
Subtractive Primaries: Cyan, Magenta, Yellow (used for print)... start with a white page and add colors. It's called "subtractive" because the pigments subtract-from (almost like covering up) the white light that is being reflected off of the page. When the color is added to the page it absorbs light. If we add magenta to a page, all of the other colors are abosorbed and magenta is the only color that is bounced back, if I then add cyan to that, the color that is bounced back switches and blue (-ish purple) is bounced back.
Where does black come in? Talk about "rich black"
Where does white come into play?
The Color Palette: Grayscale, RGB, HSB, CMYK, Web Safe RGB, Invert, Complement
Grayscale: used if you are creating a b and w peice for either print or the screen
RGB: Used for working in screen environment
HSB: fine tuning...
Also fine tuning with option>drag.
Invert (takes out black) and Compliment (keeps the value the same):
Web Safe RGB:Web
safe colors are sets of colors that will not be altered (dithered) when
shown on browsers running on a 256-color browser (or an 8 bit monitor).
Out of Web Color warning, out of Gamut color warning (color shift). Going from RGB to CMYK, going back again... show.
Screen Frequency more
often called Line Screen... a good safe bet is to do twice the
ppi as the line screen.
Color halftone: http://www.sketchpad.net/basics9.htm
What is a moire pattern?
In homework, it had you create color separations where you saw the four prints of C, M, Y, and K... any questions with this? More often than not, the printer will do the color seps for you. The Homework was a good exercise in that printer's do love it if you send them color seps with a color proof (talk about below), plus you can make sure that you are not inadvertently printing a fifth plate.
What is Process Printing used for?
So what is
the process that we go through regarding color when we go to the printer
(offset lithography) with CMYK:
Color Managment... the goods and the bads and why we are going to go onto this later.
What are Spot colors: Basically PMS or Pantone
When would you use a spot color (pass around example)? Talk about pantone---1963, leader in the industry
How do we go about using Pantone colors. What are Pantone Process colors? Which library do we pick? What is "coated" and "uncoated", why does it matter.
The books as well as the software (adobe illustrator) can be kind of confusing regarding this because it allows you to set up a CMYK color as a spot color. You SHOULDN'T do this (it will run as a different plate), unless you think that you want to go and take a bucket of cyan, magenta, yellow and black and mix your own color to throw on the press...unlikely.
Which brings us to... The Swatches
The default swatches: give a tour of the palette.
Saving a swatch: click new swatch button or sdrag color into palette.
Swatch options: the spot or process choice. The global or non-global choice.
Changing colors globally, also, dragging a new color onto an old swatch.
Other places to pick colors: double click on the swatch in the tools palette. Why would we do this?
The last color button (if you have a fill of none):
Color Filters (Blend Front to Back, etc.)
MANAGEMENT. UGH. We are not going to go into this very far in
that I think that our time is better suited to different topics in illustrator.
depends on what kind of printer drivers you have installed... take a look
at what we have.
If there is a Pantone color---you will get five pieces of film unless you convert it to Process (click on icon next to color name)
Show, talk about different examples.
Homework: finish up logos... start thinking about final projects
