    I've done a few designs on cardstock. This is the same stuff you would use for scrapbooking. I've only done this for friends and family as I am not sure there is any margin.

    I usually use 10%pwr, 80%spd, 250dpi.

    Along this line, for my better plaque customers, I engrave the recipients name on the brown presentation box. Takes about 10 seconds.

    Dee Ignore the size, when your uploading to a website, your only interested in getting the picture up as clear as possible in a size that the system will accept.. Worse comes to worse, convert your pictures to 640 x 480 pixels @ 72 ppi that will give you a large enough picture on anyones screen, still be 'fairly' clear, and probably won't exceed the size limit.. If someone wants a higher res. pic, you can email them one.. The one attached, is the same file size as your original (which was at 150 ppi), but posts much larger because is lower res. (72.ppi) It is much fuzzier, but it's also a .jpg thats been saved a few times before posting again.. If you have to do work on photos, that originated as a .jpg then save the work as a .tif and only revert back to a .jpg for the ones you post on the web..

    Thanks, Bill! I saved this one directly from the scanner at 150 and did not compress it before loading into the post. The 2nd and 3rd generation jpegs were a lot blurrier. Thanks again for the explanation.

    While I haven't been able to get a nice brown 'burn' yet, I have had some success with cheap packing cardboard. I designed a box to put my wood sculptures in, and lasered the image on the front. Rastering on the cardboard creates a nice image that 'changes' with the light!

    Marc, that looks great! For some reason, the dancer on the box looks happier than the other one to me.

    cheers, dee

I'm going to use different tabs for the final piece, but I think it's kinda cute. I'll send the settings later, I'm at my day job right now.


    Rick...you mentioned sending settings later on this box....did I miss that thread?...do you have .cdr for it to? Thanks....

    Paperboard

    One technique I use with cardstock is to purposely focus above or below the area I want to "brown". You have to play with the settings to balance darkening with resolution but you can get some interesting effects.
