I am trying to generate a TIFF file with the following parameters:
– sampled at 600dpi
– letter size (8 1/2 x 11", or 5100 x 6600 pixels)
– grid lines every 1000 units
The procedure I am using is this:
– Run the PostScript file below through Distiller, converting it into PDF
– Export the grid as a TIFF file from Acrobat.
The problem is that the resulting TIFF file has a dimension of 1700×2200, and the resolution is 200dpi.
I can change the resolution with IrfanView, but not the dimensions, because the resampling will mess things up.
I guess I need to change the default (72dpi) resolution of PostScript to 600dpi? How?
Any other suggested approach?
TIA,
