Creating a Photo on a Ceramic Tile Using the LMC 6044P Spray

In this lesson we will look at how we will adjust a photo in CorelDraw so that we can process the photo on a tile tthat was bought from home depot hat is sprayed with the Thermark spray that is designed to mark tile and glass – LMC 6044P.

My Original Image

Here is an image that we will be working with for this lesson The technique I use here is the technique I use on all my photos. I do not use the so called specialized photo processes as these techniques produce just a good image as they do. It takes 2 minutes to do and the control over my image is a lot better.

Contrast Enhancement

Select the photo. My first step is to select the EFFECTS (1) ADJUST (2) CONTRAST ENHANCEMENT (3).

Increase Tonality or Contrast

The next step is to increase the contrast or tonality of the image. In this step I am looking to create both more white area and black area in my photo. To much shades of gray will not laser very well on a tile. Our Original image is on the left (1). The adjusted image is on the right (2). The slider at the top left when moved right will cause the darker tones in the image to become darker (3). Vice Versa the triangle slider on the right when moved left will cause the lighter tones in the image to become lighter (4). Note: to see your adjustments make sure you have the lock button engaged (5).

After Contrast Enhancement

Our contrast enhancement has been applied.

Select The Unsharp Mask

Before I print any photo whether it is on my laser or on my full colour printer I sharpen the image. The sharpening process brings out the detail in my image so that pops out at you. Most photos you take or get tend to be blurry and thus seem out of focus. Shapening the image gets rid of this issue. To access the Unsharp mask command go to BITMAPS | SHARPEN (2) | UNSHARP MASK (3).

Unsharp Mask Dialogue Box

The Unsharp dialogue box is pictured above. The original image is on the left (1). The sharpened image is on the right (2). The two sliders or controls that I work with are the Percentage slider (3) and the Radius slider (4). When it comes to porous material such as tile I usually slide the slider up to 500 (3). The Radius I adjust as is needed. But the more porous the material the more I slide the slider or increase the value. I do not typically adjust the Threshold slider (5).

Image Sharpened

Here is our Image Sharpened. Notice our our image pops now.

Here is Our Convert to Black and White (1 Bit) Conversion Window

In the Convert To 1 Bit dialogue box you can see that our image has been transposed to strictly either black or white (2). Our original image on the left (1) is the grayscale image that is still composed of shades of gray. There is a bit of detail lost but not much – but htis is critical you want to lose detail in the image so that there is more detail when you laser the image in the tile. You have a number of choices to use in the conversion I typically use Jarvis, Stuckey or Floyd Steinberg (3). The Intensity slider decreases the amount of diffusion that is done in the image in that it becomes lighter.

Error Diffusion Image

Our image after it has had the error diffusion algorithm applied.

Our Finished Image On The White Tile

Here is the finished image on a 33 cent Home Depot tile. The reason that I think this tile looks so good is because I have taken out a certain amount of detail which has accentuated the remaining detail in the tile. When you look at the hair it jumps out at you and the face is easily recognizable with the original. If you remember what our original image looked like after we sharpened it you may be surprised to see this image. But again I reiterate that reducing detail actually increases detail. So even though it looks bad on the screen it will look good on the finished product.
