Wondering if others have found solutions to this - when I layer images, the edge of the transparent sheets remain visible (see solid line along the top of the image). What brands of transparent sheets are others using ? Any suggestions or tips to avoid this ?

Tried cyanotyping on white t shirts today. Any tips on how to get the white parts whiter ? I’m wondering if my printer might be low on toner because when the “white”parts are turning pale blue. I tried reducing exposure time which worked a little but not totally. Grateful for any tips !
