[gradsusr] High resolution images problem

[Júlio Barboza Chiquetto]

Hello all,
I've had some problems generating high-resolution images with printim (I am
using version 2.0).
It seems that, with, a white background, the text gets somehow fainter.
The more pixels I used in the commands, the more the text faded.
For these images I used:
printim image1.jpg x5000 y5000 white
printim image2.jpg x500 y500 white

For image 2, I used 10x less pixels but the text is much clearer to read.
There must be something obvious I am missing here, but I am afraid I don't
know much about digital images.

I suppose I could change x and y axis fonts thickness and size, but I am
not sure it would work.
Anyway, I don't understand why this happens and am looking for a reasonable
solution.

Kind regards,

Júlio B. Chiquetto,
