Screenprint Induction notes


  • SCALE / RES : Check res = 300ppi - If you're going to scale up then scan higher res, untick resample to change res to 300 (this will altar width/ height) - then retick resample and you can change w/ h to exact measurements
  • COLOUR : to remove colour in RGB - Image, Adjustments, Desaturate
  • CONTRAST : Change either using levels - lay arrows on top of each other or image, adjustments, threshold - move single arrow 
  • PRINT : to black and white laser printer - in print studio

  • TO ADD 2ND COLOUR - do in new layer - add block colour over line drawing? 
  •  TO SEE WHAT TWO COLOURS LOOK LIKE PRINTED - change panel next to opacity from normal to multiply 
  • if you don't want to see through - just select, rub out colour 
  • CHANGE LAYER COLOUR TO REP INK - you can use hue/ saturation adjustment layer to colourise - just turn off layer when negative prints
  • You can still nock out shapes, add them in just using shape tools - if you draw a shape you can click across layers and fill it on multiple ones 
  • SIMULATE PAPER STOCK - add another layer - behind background - multiply scanned image so you can see through the white page (make sure all adjustments are applied just to the layer below)
  • MAKE POSITIVE TO PRINT - duplicate coloured layer, lock transparency (b and w check board) - locks checkered pixels - then fill 

  • TURNING IMAGE TO CYAN MAGENTA etc. i.e. A photo - change to CMYK, go on channels - next to layers menu to see layers separately 
  • place image in illustrator, print settings - A4, output settings - change from composite to separations to see different colour separations - change frequency to no higher than 50 !! (so dots come out) - can make bigger (30 about right). All colour dots need to be at different angles too in rosette formations - 15, 75, 105, 155
