One of the problems that you have when you are looking at do a mural is typically the photo that you are working with is to small to work with. This was the case when I has creating this mural. For example the photo I was able to retrieve off the Internet was approx. 1.5 inches by 2.5 inches and had a resolution of 300 DPI. Now this is not going to be a big article when it comes to talking about resolution and DPI versus PPI but we will need to spend some time talking about what is the proper PPI to have with a photo. Note: when we look at a photo and we look at its resolution although it is expressed in DPI it really should be expressed in PPI. (which is pixels per inch) DPI is for printing only. As I have already mentioned the original image is 1.5 by 2.5 at 300 DPI. If we take a look at the this granite mural you will see that is 24 inches wide and 36 inches high. If i just resized the original image to this size it would never even come close to engraving properly. For this reason we need to get the photo up to a higher PPI so that we can print it properly. What I am shooting for here is a photo that is 24 by 36 and a PPI of 300. Although I do not have to have it at 300 PPI because I am making it so big if I leave it at 100 it will not process properly when I run it though the unsharp mask and conversion to black and white. Fo this reason I created a photo that had a resolution of 300 PPI at 24 by 36.
I had a request from a seminar attendee on giving them some guidance on working with customer supplied .doc files.
Here is the question: As per our discussion I have attached one of the files I am presently working with. The customer is requesting 1/2 inch letters on a 3/4 x 3 inch stainless steel cable tag. Here is what I have been doing. I take the list from windows and copy and paste it onto an an excel spread sheet. When I have the numbers (first column in red) in excel I set my font size. I then highlight the column or columns and press the down arrow by "copy" and "save as picture". Then I paste it to my Corel work sheet, unlock it and then as I can transfer each number to a cable tag I set the width to 2.1 inches and the letter height is already good. I am printing approximately 150 tags x 2 for nineteen different jobs with one letter changed i.e.: JA-HRTD-LHIC04A-1 only the letter in red would be changed for each of the nineteen jobs i.e.; A,B,C, etc.
In this tutorial we will look at how to take a photo and create a cutout in an ornament. Our sample is listed below. It was created by Tim Kane. He has done a couple I have seen and I know that there is a number of you that would like to know how it is done. I can think of at least 3 ways I could recreate this maybe 4. This tutorial will focus on an old fashioned way that has been around for a long time. We used this technique a lot when I was spending more time in PhotoShop.

Typically when it comes to testing materials I have two methods. One involves creating a black box in Corel and just engraving the image. The second involves an actual test file that uses the colour mapping in your laser driver. Typically on most material such as plastic or wood I can adjust my power or speed on my machine as the material is engraving. Adjusting my power while the machine is running allows me to see my results as the machine is working. This makes it easy for me to quickly get the proper power and speed. However on product that uses Thermark / Cermark. I can not see the results of the mark until I clean off the spray. This makes using the black box not very good for this application. … Continue Reading
In this lesson we will look at how to set up a default workspace in CorelDraw X6. This is typically what I do for my computers. You may do it differently depending on your workflow and your likes and dislikes. In X6 CorelDraw has introduced Style Sets which is where we make some of these changes. This is a departure from previous versions. Also it is important that you make the changes in the default pen width so that it is set to hairline. Thus when you draw a vector shape such as a rectangle it will cut on the laser. … Continue Reading
This was a request from a customer on how to recreate the text so that it flows in curve along the top of the text but is still straight at the bottom. We do this using the Envelope command in CorelDraw. The Envelope command is a very powerful tool that is one of those tools that you tend not to know about. It can create a lot of effects
This was a file that was sent to me by a customer that had issues with an AutoCAd file imported into Corel where it would triple cut and jump all around without completing to cut one whole object. It would just cut the individual segments. In the old days we would have had to delete all the overlapping segments and join all the broken segments into one overall object. To do this requires us to use the Smart Fill tool in CorelDraw. This tool is excellent for creating a closed object where there is not closed objects. Although we do not have to get rid of our extra layers I will do it more as a house keeping excursus. … Continue Reading
