Like the title said, I need help on how to increase the standard DPI of 72 to at least 300 DPI. I need this because I made a drawing for a friend who is going to use it as an image on her business postcards. Is there a possibility? I already found out that although Oekaki is an excellent program to draw, it probably isn't the best tool if it has to be (professionally) printed... help help.

Well, it's quite simple really, you multiply the dpi by the size in inches you want the final thing to be and you have the number of pixels.
For example, 300dpi for a 2.5x1.5" card would be 750 x 450 pixels.

While oekaki isn't intended for high resolution work, the applications support it (Lascaux Sketch has recently been updated to handle higher resolution a little better).

Hope that helps...

It was a big help. I also found in psp9 where I can up the dpi. I just love drawing with lascaux, like it even better than photoshop :D

you're gonna make him blush Joyce..he wrote it!

It's worth pointing out... Photoshop and Lascaux Sketch
It's like Screw Driver and Dish Washer.

So...let me see... its sketchy...if there's a photo when the driver screws the dishwasher?

Oy, now I have a weird visual in my head :-D

this was a great question (the original one..lol) that I've always wondered about. Thanks for the info!!
