Here are requirements for the assignment:

• The initial card must be exactly 2 inches by 3.5 inches. With one run, translating the card if necessary, print a single copy of your card on a sheet of paper. (It might be easiest to put the lower left corner of the card at the origin (0, 0) of the Postscript coordinates, that is, the lower left corner of the page. Note that your card should be 144 points by 252 points.)
• Produce another copy of the same card, but magnified by a factor of 2.5 and printed horizontally, so that the final card will be 5 inches by 8.75 inches on one sheet. (You will need to rotate by 90 degrees, scale by 2.5 in both x and y directions, and translate by some amount. It will require some thought or experimentation to decide which order to do the three operations in.)
• In a third run produce at least 5 copies of the output card at the initial size. The Postscript code that produces these 5 copies should employ a Postscript loop. (See pages 51-52 and Chapter 7 of the Blue Book (PDF, 847k). I also handed out source that did something similar to this.)
• The outer 2 inch by 3.5 inch boundary must be stroked with a thin line.
• At least one piece of text on the card must either be centered or right justified, using the stringwidth function, so that the text would remain centered or right-justified even if the font size is changed. (See the Blue Book, pages 42-43 for right justification, and pages 58-59 for centering. See also my handout with a card on it.)

Here are some additional features that I would like to see you incorporate into your card:

• The use of some ``graphic object'', e.g., some picture made up of one or more paths.
• The use of an outline around characters in a string. (See the example on page 98 of the Blue Book.)
• The use of a clipping path, especially one involving a string of characters. (See the Blue Book, pages 103-104.)

Finally, try to make it look interesting. Be creative. Don't just copy the book or one another.

Good luck!
