To avoid aliasing problems on a 600x600 DPI printer, generate a Black and White BMP file at full 600 DPI resolution and print it at 100% scale. This method utilizes the printer's resolution effectively, minimizing jagged edges in the output. For optimal diffraction grating quality, ensure that the plotted lines are spaced appropriately to prevent merging. Additionally, consider printing the diffraction pattern at a larger scale and using film photography to achieve the desired size without compromising quality.
PREREQUISITESThis discussion is beneficial for graphic designers, optical engineers, and anyone involved in the production of diffraction gratings or high-resolution printing techniques.
600DPI doesn't necessarily mean the dots are 1/600th of an inch, just that they are spaced at 1/600th of an inch.Paddyster said:I'm making diffraction gratings using the printer mentioned and transparent overhead projector sheets. The lines I plot however have jagged edges and if I plot them too closely they will merge into one. How close can I plot them and still get the best quality diffraction gratings and thus diffraction patterns and how do I combat the jagged edge problem?
