Working with Black Granite – Adjusting a Picture of the Eagles

Adjusting a Picture of the Eagles

In this example we will be lasering an image of an eagle onto black laser tile. Figure 1 shows a photo that I bought off the Internet. I am using this image because I want to see what the effect of having our background image being a bit out of focus and to see how it appears on the tile.

First of all we need to convert out image to grayscale in CorelDraw. To do this go to IMAGE | MODE | GRAYSCALE.
With our image in grayscale we need to adjust the image without Contrast Enhancement. To access the Contrast Enhancement command go to EFFECTS | ADJUST | CONTRAST ENHANCEMENT.

Sharpen the Image

  1. Hola buenos dias desde España.
    Quisiera saber como pintar en blanco sobre granito negro.
    Mi empresa se dedica a las lapidas y me interesa que el gravado sea lo mas blanco posible.
    Gracias por su ayuda.

  2. With our image in grayscale we need to adjust the image without Contrast Enhancement. To access the Contrast Enhancement command go to EFFECTS | ADJUST | CONTRAST ENHANCEMENT.

    What does this mean? You say we need to adjust the image WITHOUT contrast enhancement, but then take us to contrast enhancement without instruction! What are we supposed to do here?

  4. Dear Mr Clarke,my Name is Tim kluge from Germany and first of all i want to say sorry for my bad english
    I just bought a speedy 100 but till the laser arrive i am working with a rayjet
    I would like to engrave a Photo on black granite but it dont works
    I do it like you do it in your video (processing a picture in coraldraw to laser on a black granite tile)
    The only think i cant do is the step: convert into black and white
    Someone told me that it will be also ok to let it in grayscale before i invert it
    Can you tell me something helpfull?
    How much Power and speed you would use by a rayjet?
    Even if your Video dont help me at this time i would like to say thank you for all your other thinks in YouTube

    • Hi Tom sorry for the delay. On a 30 watt ray jet I am thinking 100 speed and 60 power. The main issue on this material is to much power which removes too much material. Once you get your speedy 100 change the halftoning to Jarvis
