    That's why I included the lesson about dpi and pixels above.

    We plot jpgs all the time at 200dpi but a A1 sheet 36x24 often other stuff smaller size and the secrect is in setting up your sheet plot size as pixels our A1 is 801mm long so pixels = 801*200/25.4 = 6307 pixels in inches. so 5mm =5*200/25.4 = 39 pixels @300 dpi = 59 pixels

    Hi. Ok so this is what I have done so far at 300 dpi:
    I need 5x6 mm image which is approx 0.19x0.23 inch so I need 57x69 pixels. Correct?

    Now when I plot I make a custom paper having dimension 57x69 pixels. Correct?

    Now this is where I'm still confused:
    In the plot scale of the plot manager I asks to define 1 pixel = x units. What is this and what value should I put here?

    Please correct me if I made any mistakes in the calculations or setting the paper size

    The thing is my paper size isn't defined. I will be using the laser to reduce a piece of polymer as paper so I can use any size polymer I want.
    This is what I've done so far at 300 dpi:
    5x6 mm = 0.19 x 0.23 inch
    the number of pixels needed are:
    57x69 pixels.

    Since I'm free to use any size paper I want so in the plot manager I have made a custom paper having dimensions 60x70 (to give a little wiggle room). Now in the plot scale there is the option of 1 pixel = x units. What is this and how do I set it?
