To create a digital negative:
Using Photoshop, create the artwork that you want to cyanotype,
sized appropriately for the piece of knitting. The finished will be the same size as the negative.
Convert the image to grayscale.
Flip the graphic from left to right, so that any lettering is now backwards.
You do this because when printing, the negative will be placed face down, ie. ink-side down.
Invert colors to make it a negative.
Print the finished graphic onto inkjet transparency film.
Get some Pictorico Premium Overhead Transparency Film (OHP) from Prof. Ireland.
Using an inkjet printer, print the reversed image onto the OHP film
at whatever size you want the final image to be but as big as letter size.
Since this is a contact printing technique whatever size you make the negative will render
the same size on the printing surface.
