In this tutorial we will look at how to engrave two different logos on a wine glass. Each logo will be located on opposite side of the glass. This can be a hard job set up unless you put a little thought into it. It is easy in the Trotec software as I can bring in two separate jobs into one job. It is easier to set up a logo that is duplicated on either side of the glass. However logos of different sizes need to be set up with a little more thought. In this tutorial we will show you how easy it is. Remember this can be done because the rotary attachment turns the glass exactly around. This means there is no slippage on the glass.
A Wine Glass with 2 Sided Engraving
Here is a picture of our wine glass that we will be creating this tutorial for. I have a logo on the front side and some text on the back side. This is a pretty common type of setup that you will come up with if you are asked to do a two sided design with two different images.
Create Your Logo and Resize it
I have brought in my logo and resized it to the size I want. which is 2.25 inches long and .62 high (1). I have rotated it 180 degree (2) due to the way the cones are situated in my rotary attachment.
Print Your Logo
We need to print our logo and send it to Job Control. Select the Trotec Driver (1). Because we have two images we need to make sure that “Selection” is selected (2). Select Preferences (3) so we can place in our page size.
Set Your Page Size
I have created a page size that is 10 thou bigger on both the Width and Height. My image size is 2.25 by .062. My page size is 2.26 by .63 (1). Click OK.
Reposition the Image to the Center of the Page
Before we print we need to go to Layout (1). Select Reposition images (2). Center of the Page (3). Our image will now appear in the print preview.
Create Your Second Set of Artwork
I have created my second set of engraving. It is just text. The width is similar to the logo – 2.256 (1). The height is .815 (1). I have rotated the text 180 degrees.
Place in the Page Size
I have added in an image size plus .010 into the width and height section of the laser driver (1). Width is 2.26 and the Height is .63. If we look at the original size these values are .010 bigger. This accounts for the .005 margin that CorelDraw places on a drawing. The original Width is 2.25 and the Height is 0.62 (2). Select your power and speed settings.
Set Your Power and Speed
I have set my power and speed to allow me to run at maximum speeds. Note: For a lot of designs you never actually reach full speed as the distance to start and stop is to short. So even though we have 100 percent in terms of speed 35 percent might be more applicable because of the shortness in engraving width. Click OK and Than OK
Because we have two objects on the desktop we need to make sure the image we are printing is selected. With that image selected than we need to select “Selection” (1).
Reposition Our Image to The Center
First we need to select the Layout Tab (1). Select Reposition Images to Center of the Page (2). This prints only the image that appears in the preview window (3). Click OK to send the logo to Job Control
We Need to Send Our Second Image to Job Control
Make sure your image is selected (1). When the image is selected you can see the image attributes in the property bar (2). When you print you can move over the print dialogue box so you can see the selected logos dimensions. Place in those same dimensions into the width and height in the print dialogue (3). Remember that the width and height have to be 10 thou larger in the print dialogue box to account for the .005 loss in CorelDraw. Click OK to send this to Job Control
Reposition to The Center of the Page
Select the Layout Tab (1). Reposition Images to the Center of the Page (2). The print preview window shows us that our image is ready to be sent over. Click OK.
Setup The Rotary Attachment in Job Control
We need to select the rotary attachment (1) and let the driver know we are using the rotary attachment (2). I have placed in my diameter (3) of the glass. It is the same wine glass we have used so the diameter is 3.2 inches or 10 inches in circumference (10 / 3.14)
Position Our First Logo in Job Control
I have used the Laser machine to position the head where I want the laser to start in terms of the left and right movement. (1). Because I do not have to worry about positioning on the glass I only have to worry about the left and right location. The X co ordinate is 21.54 inches. Now we need to figure our Y location. Our circumference is 10 inches. We are putting in two logos so each one will occupy 5 inches. We are measuring from the middle (2) so we need to place the logo at 2.5 inches. The reason we have to locate from the middle is because our logos are different sizes. We can not locate from either side as one is longer that the other and they would not line up properly. We thus do it from the middle. This allows us to accurately place the image. Now let us look at why we have chosen the location. Our glass is 10 inches in circumference. We have broken our image into two 5 inch sections. We need to place each one of the logos in the middle of this 5 inch section. The middle of a 5 inch section is 2.5 inches. Thus the middle of the logo is 2.5 inches. I am measuring the middle of the logo so it needs to be at 2.5 inches. I have placed the logo at 2.5 inches (4) – I am measuring from the middle (2)
Locate the Second Logo
Now I need to locate our second logo at 7.5 inches. I have placed the image at the same X location 21.54. I have placed the image at a center location of 7.5 inches (2) (5 inches + 2.5 inches). I now have each image located where I need them. We are now ready to run the job.
