When PETG-HF came back in stock, I ordered quite a bit to restock.
A recent print in PETG-HF Green (33500) rolled over from one spool to the next, and the difference in color is very noticeable.
I went over my invoices and checked the empty boxes to be sure I was using all the same material.
I found colour variations can come from the depth of colour your printing , a single layer for example would be lighter than multiple layers .
This is a print i did a while ago , same filament , same roll just a variation in its depth with the top being overlayed with clear filament
Thank you for the input.
In this case, the print is about 12mm thick and the demarcation is in the Z axis where the changeover occurred.
When I get back in the office I’ll do a color comparison with the swatches.
That issue looks more like a sheen issue as seen on a benchy which would imply speed variations , the only other time ive come across something similar would be slight variations in colour from different manufacturers , assuming your talking about the far left side as compared to the right hand side and its not just the light
Layer lines run top to bottom in the pic (left side was on the bed).
The sheen is consistent, though the right side shows that the filament didn’t go through a drying cycle before printing.
