How to Mark More Clear Photo by Ezcad Software
Published 2019-06-25 by the Weihua Laser engineering desk.
Setting The Right DPI For Image Clarity
In EZCAD software, the DPI parameter controls the density of the marking lines. You should generally set the value between 100 and 500. The correct number depends on the spot size you are using. A smaller laser spot allows for a higher DPI value, which produces a finer picture. If you try to force a high DPI on a large spot, the marks will blur together.
Adjusting Power To Avoid Washout And Shadows
Laser power is the second critical variable for photo marking. If the power is set too high, the material burns or bleaches, turning the image white. If the power is too low, the image becomes too dark and loses detail. You must run tests to find the balance. The source text notes that more experiments are needed to match the actual effect of your material.
Selecting High Resolution Source Pictures
The software cannot invent detail that is not in the file. Normally, the higher the pixel count of your selected picture, the better the final mark will be. A low-resolution image will look blocky even if you adjust the machine settings perfectly. Start with a high pixel density image and let the software downsample it to the correct DPI for your spot size.
Compatibility Across Different Laser Sources
This software logic applies to a range of Weihua Laser equipment. Whether you are using a CO2 laser marking machine, a Mopa laser, a fiber laser, or a mini desktop unit, the parameter rules remain similar. The interface supports these different systems, allowing you to transfer your settings knowledge between machines. This helps maintain consistent output quality across your production line.

Buyer Questions
Questions On This Topic
What is the recommended DPI range for photo marking?
The standard range is 100 to 500. You should choose a higher DPI if you have a smaller laser spot size, as this creates a finer picture.
Why does my laser mark look white?
This usually means the laser power is set too large. The beam is burning off the surface detail. Reduce the power and run another test.
Why does my laser mark look too dark?
If the image is too dark, the laser power is likely too small. Increase the power slightly and check the effect on a scrap piece.
Does the image resolution matter for the final mark?
Yes. The source text states that the higher the selected picture pixel, the better the result. Low-resolution files will not produce clear marks regardless of settings.
Can I use this software for CO2 and Fiber machines?
Yes. The software works for CO2 laser marking machines, Mopa laser marking machines, and fiber laser marking machines. It is compatible with mini, desktop, and enclosed types.
How do I know if my spot size is correct?
The DPI setting should match the spot size. The larger the spot, the lower the DPI you can use. The smaller the spot, the higher the DPI you can set.
