lithopones using 1/2" corian

[t-townwilson]

A while back somebody commented that he (she?) mostly used 1/2" Corian for lithos, saying it provided greater detail and more interest. I have some 1/2" white Corian that I would like to use, but wondered about depth and height settings for the 1/2" as opposed to the more commonly used 1/4" material that I normally use. I tried searching the forum for this post, but I was not able to locate it. Ant suggestions? Thanks in advance!

You're in luck.. I happened to see your post. And I have used both 1/4" and 1/2" corian to make lithos. Most of my 1/2" litho were made using a depth of .375 which should be the same ratio of using .185 for 1/4 inch corian if my math is correct. Check it out with your calculator I could be having a senior moment.
This particular litho has a height of 666. Attached are two photos one showing without light and other with light. You can see the depth in both.

Canemaker, 1/2" litho. John what do you think would be the settings for 3/8" corian, I am looking at making
a litho for a company around 6" x 12" for their company logo. I don't have any 1/4" that size.

I've carved a couple lithos now with 1/2" corian, and I am not happy with the lighting. I used a depth of .375 and a height of 900 and bit optimization at best, but the faces are so bright they are almost "unearthly"! I'm going to play with different settings.

When I change settings on the screen in Designer 2.007, the image is immediately very sharp, then suddenly blurs. What causes this?

[Canemaker]

I've asked that same question before about the image being very sharp then suddenly blurs... and I was told by Begerud a Senior Member that:

Seriously, I think the flash of the clear image is actually the original real image. The software quickly calculates a WYSIWYG image that the machine can actually carve and displays that. The real image is too high a resolution for the 1/16" ball to follow so the machine shows you what the 1/16" ball will create.

[t-townwilson]

That makes some sense.

What about the issue with settings for 1/2" corian? Any suggestions?

try changing the default carving bit for the project to the 1/32" bit and see if you can see a sharper image in Designer. I did this a few days ago when someone had issue with poor carving quality with too small text and there was a noticeable improvement in the as displayed carving due to the smaller bit allowing for greater detail.
