Gandi 3150 Resolution

[Scott Anderson]

We are trying to print very small letters/barcode down to about 1/16th inch. It is completely illegible. We are currently using 3x6 15 pass w/200% ink. Digitech inks. It did not get any better in 4x8 mode and can't seem to get the machine to go to 6x12. Have tried the turning machine off, computer off, and IO boards off as suggested on another thread. I still don't think thats going to get us there anyhow. Does anyone know weather it is even possible on this machine to get small print legible???

Run It uni.. Good xy calibration will get you there..

Most machines your going to need to print unidirectional that small to work.

Thank you. We have tried unidirectional and will really work on tweaking x/y on the heads. will let you know....

Also dial in the head hight and tweak the microns! Slow down the carriage too. This plus uni should do it.

This is 1/16th" text below the eyeball. 300x600 200Density
bidirectional. I don't try print anything smaller.

Also if its a RICH color you are running, you have a better chance of misalignment between the different head colors....single color black Much easier to align in that case.

Thanks everyone. We got about 90% of the way there. Going to keep tweaking in hopes of the final 10%.

 

[Scott Anderson]

Oh the color is grey so probably worst case. And thanks cwb143 for the pic.

Scott, can you rip color replace the gray from a 6 color gray to only a % of black. At that size the color shift will be minimal.

I forget what test pattern it is where you can evaluate them, but you might want to tweak your head voltages, they tend to get a sort of a blurry effect when they are out and it makes a big difference. Also have you tried force_dpi_x 600 force_dpi_y 1200 and a snapkill and restart from the console? You could also manually up the pass count past 24 and slow it way down.

Good luck!
