I know this is been asked a million times....but would it be ok to run 18pt board once a month, say 10,000 sheets? It's a really soft, light board, long grain.

I didn't think about the durometer. The rollers are 3 years old. I am a one man shop and don't do a whole lot of impressions, but I run mostly spot colors so there are a whole lot of washups.

Hi there, My water setting is getting very high, up to 90 today. All my stripes look good. It's been fairly gradual. 6 months ago I'd run at around 50. 2 years ago around 35. The press is running great and prints great. Any suggestions?

I think I figured it out. The head suckers were set, with the set screw on the bar, angled a little too far forward (away from the press). This changed the timing of the sheet to the feed rollers slightly. The feed rollers were also a little loose (compared to the timing). Fixing this allowed me...

I'm not sure what I did different, but the indicator on the feeder panel says the sheet is really early. The panel at the delivery says early. The press runs great and register is dead on. I use the knob on the non op feeder panel to adjust and nothing changes. Any ideas?

Swapped boards 3 and 4 and seems to be working. I was able to make a few plates with all 32 diodes, but then got the correct error that diode 29 is bad. Runs with diodes 0-15 fine. I'll keep my fingers crossed.

I'm swapping boards right now

Error Code E4e03

PTR4300s Platerite

So, I get the error intermittently. Sometimes I can make 10 plates, other times it takes 5 tries to make one. Checked laser power, number 29 is bad. Change option to 0-15 diodes and still get same error. It says it's board 3 overvoltage. Sometimes it won't finish diode test. Sometimes it says...

So I ended up printing a full sheet filled with screens from an uncalibrated plate, input the values read and voila, dead nuts first try. Thanks for the help everyone.

True. I use Toyo ink that is formulated as you suggested. It prints beautifully.

I'm printing on an almost new SM52. New rollers, new blankets, new Techkon spectrodens. My Screen 4300S was just calibrated by agfa. The press runs and prints like a dream. If I get the plates right the only variable is me and my skill. That's my theory and I'm sticking to it 😆

Great wisdom guys. On an uncalibrated plate my 50 was printing 72 on uncoated not very smooth stock. I think I'll just work it down with a well distributed curve and call it a day. Pantone tints are a bitch and there's no way around that.

I understand making plate curves for 4 color process, i.e creating a plate curves to hit certain tvi for a standard like fogra, but what about single color screens like you would see in a business form? A dot gain of 15 on a 50 is pretty extreme. How should I build my curve? Make a plate, hit...
