AM screening and FM screening are two main printing techniques that utilize different methods to represent color images.
In AM screening, variations in tone are achieved by altering the size of each printing dot. Within a fixed grid, the size of each dot can vary, thus creating different light and dark effects. This method is suitable for images with large areas of similar tones as it can provide uniform color coverage and more precise tone control.
On the other hand, FM screening achieves tonal variations by altering the density and spacing of dots. This means that the size of the dots remains constant, but their arrangement and distribution vary. The advantage of this method is that it can provide higher image detail and contrast, especially in images rich in textures and details.
Here are some examples for comparison:
The FM method can present more details, such as textures and hair strands.
The AM method provides better color coverage on large areas of neutral tones, and the noise is not as noticeable.
Choosing between AM and FM methods depends on the characteristics of the image and the desired printing effect.
- If your image contains mostly lighter or neutral colors, you could use the AM method for better color results.
- If your image contains more details and lines, you could use the FM method to present the fineness of details.
We suggest you try printing a small part first to find the best printing method that suits your design.
