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.

Laser Engraving Wood

Laser Engraving Wood

It may seem trivial to talk about laser engraving wood but considering that it is one of the products that most of us do a lot than we should spend some time talking about it. We can talk about raster engraving and vector engraving as two separate processes when it comes to wood.

Raster Engraving Wood

When a laser is raster engraving (Figure 1 shows us some samples of raster engraved images) the laser marks with a back and forth motion. This motion is similar to what you would see with a laser printer or an inkjet printer. The laser slowly moves its way down the table. The amount of the movement is dictated by the dpi that has been chosen in the driver. When we are engraving a message in wood we use the raster movement of the laser to create the message. … Continue Reading

Thermark (Cermark) (Cerdec) Metal Marking Spray

Cermark / Thermark Metal Marking Spray

The TherMark process utilizes marking materials, or “inks,” available in various forms, which are applied to surfaces to be marked. The ink is then selectively fused – using patented laser marking technology – to the surface with a regular industrial marking laser. Finally, any excess ink is easily cleaned from the surface. The inks are scientifically formulated to make a permanent, chemical bond to surfaces, without compromising or damaging the material being marked.

TherMark marking materials are available as paintable liquids, aerosols or adhesive transfer tapes. The paintable liquid may be applied to surfaces with a brush, sponge or air sprayer. After fusing with the laser, any excess paintable liquid or aerosol spray can be cleaned from the surface by simply rinsing with water. Tapes are applied to surfaces using their own light adhesives. After fusing with the laser, the tape is lifted from the surface, carrying away any excess marking material. The used tape is then discarded.

Regardless of the application, the end result is a durable, high-contrast and high-resolution mark. (as appears from the Thermark web site) … Continue Reading

Creating a Custom Colour Swatch Chart

One of the things that can be a problem when you are sublimating is creating colours that are the same as on your screen as what you get on your finished product. One way to help solve this problem is to create a swatch of your colours and print the swatch out so that you can compare the colours on your screen with what you have printed.

Creating the Swatch in CorelDraw Version 8 and 9

The colour chart file located below is a CorelDraw 8 file that has been created by McCollough for those who wish to print out the standard RGB chart. Each one of the color swatches has its appropriate RGB numbers attached to it. All you need to do is open the file and print it out on you material that you want to use for sublimation. … Continue Reading

Working with CorelDraw’s Colour Palette

One of the more overlooked features in CorelDraw is the use of Colour Palettes. Typically when we install CorelDraw, the program loads its default palette. If you look to the right of your screen you will see the colour palette – it is the bar that holds all the little squares of colour.

Let us look at the colour palette.

1. The first thing that I will get you to do is to open up the colour palette browser. This is found in WINDOW|COLOUR PALETTES|COLOUR PALETTE BROWSER – see Figure 1. … Continue Reading

Blower Specifications for Epilog Laser Engravers

We have outlined in this article what we feel is a good blower for you laser engraver. This specification is based on an installation where you are no farther than 20 feet from the laser machine to the exit of your exhaust pipe out the wall. The attached blower is available at Busy Bee tools. We would suggest that you also purchase a gate that allows you to restrict the flow of air for thin materials.
Figure 1 is a picture of the blower that we suggest. It is a 1 hp dust collector blower.
