Cyanotype (16th Round)

Almost 2 months since my last sun-printing.

Same as last round, just exposed with the dark transparencies prepared with the methods initially used for tri-colour printing, and then printed over the other colours by Epson printer.








A correction from my previous test. The length of the paper (Daler Rowney Fine Grain - Cartridge 160gsm) did shrink a mere 1mm after dry, but the misalignment you see here wasn't due to the shrinkage of paper. I was surprised to find out that the printout of a 18x13.5cm image will become 18.3x13.72cm in size whenever I choose high quality output. Though the printout size is correct if I choose normal output which is only suitable on plain paper. To rectify this problem, I need to reduce the image to 98-99% on white background color, but not the image size in order to keep the printer alignment on A4 paper setting.

I do like the misalignment. But I too want to have the control to minimise it a little.  Like the first gif file on top (the bus no. 7) which I've reduced the image by 1%.
