Objectives |
Studio Fundamentals: To learn to use computers as a tool for creating art,(Adobe PhotoShop, scanning) and print a four color/ silkscreen. To become familiar with process color printing, and understand the differences between CMYK and RGB color. Concept: To gain experience in working as part of a collaborative team. |

Project Overview |
Working collaboratively, create a four color/ process silkscreen, using digitally produced color/ separations.

Process |
Preliminary: Before coming to class, review the thematic concept of Collaboration as found on the website. Also read the discussion Media for Unit X. Review the Project References above. Step One: Scan an image into a computer These are specific instructions for Adobe Photoshop version 5.0 and Desk Scan at Arizon State University's Computer Commons classrooms. For other venues or programs, instructions may be slightly different. See Photoshop manual for newer versions.
In the Desk Scan menu:
Name your file and move it to a disk or the "shared space" on the desktop With your partner, move to another computer in the room to complete next steps. Step Two: Change image to CMYK color If
you want to alter your image in PhotoShop,do it at this point.
Step Three: Look at the color separations
Step Four: Create Halftones Go to File > Page
Set up > PhotoShop 5.0.2 Setting the halftones at an angle creates the "rosette" pattern below when using a regular halftone. or the cross-hatching effect below when using a "line" halftone
(regular halftone) ......("line" halftone) Step Five: Print
Separations Step Six: Create
Transparencies Step Seven: Print |

Critique Ideas |
Students learn primarily by hands-on involvement in this assignment, and also by magically seeing the optical mixing happen before their eyes. Points to discuss might involve the following:
