 Posted: Sat Oct 08, 2005 7:18 pm Post subject: Help Creating a DPI effect. |
 |
|
I have a gray scale tiff image that will be printed on a corrugated fibreboard carton. I need to show what this image will look like at 45 DPI when viewed on a screen and printed out in a PDF file. How would I show the actual 45 DPI in the image itself? I Have seen images before that are in 45 or other DPI but for the life of me can't figure out how to do it. I have Photoshop 4 here at home on my laptop and am about ready to pull my hair out trying to figure this out. I know if I had a LaserWriter, I would just assign a DPI to the image when it goes to the printer and it would print out at 45 DPI. This effect is what I need to be seen on the screen.
I don't have to print it out and scan it to show the 45 DPI effect, do I?
Any help is appreciated and thank you beforehand. |

Use
Filter>Pixilate>Color Halftone.
make sure your image is greyscale
Set Channel 4 (Black) to 45
then depending on the size resloution of your imae set max.radius to somewhere around 6 for 300 dpi.
This is onbly a guestimate but looks about right dot size to me
