Fuji Plates vs. Saphira Plates

[adamsg]

Hi,
We've used fuji plates for years, never a problem. We are considering a Heidelberg workflow. Anyone out there used Heidelberg Saphira plates for long periods of time? How do they stack up against the Fuji product.

 

[adamsg]

I should have said this in the original post, the Fuji plates we currently use are the LH-PJ.

 

[Mike Herndon]

We used the Fuji LH-PJ for years and years, in my opinion it is great plate and tough to beat. Last year we switched to the Heidelberg Saphira PN. They run almost identical from a print stand point, same characteristics roll up etc. They seem to carry a little more water than the Fuji. The only thing we adjusted was our alcohol sub, we went up 1 oz per gallon- that's it. If we start having problems with the plates 99.9% it can be traced back to the processor. These plates are much more sensitive to the processor chemistry than Fuji, at least in our shop. We can get around 200imp off the plates before we start having problems.

I'll add one more thing, Heidelberg was very helpful when we did the switch. The few issues we had we're resolved quickly by tech support. Just make sure your prepress stays on top of the routine processor maintenance. Whenever we've had plate issues it usually came back to the processor and no one cleaning it etc etc.

We have been using h-berg saphira plates for 5+years now, they run great, the plates and chem are actually agpha products.
We have a finger printed color management were 4 color process is almost exact to our color proof.
We used fuji back in the day and our head pressman has been here almost 20 years and prefers the saphira plate to the fuji by far.
Cleaning the processor is a dirty stinky job but if you clean it every 300 plate or so and keep the inline filter(s) from the waste tank to the drain changed the processor will last years.
The chem is not green but there has been talk about a chem free plate from h-berg but its just talk so far as I know.
The pro-setter is a great devise also but it does have some expensive parts (filter $350 change every year or so) so we pony up for the service contract the compressor is in the upper thousands to replace.
Hope this help you out.

CSM 20,

Hi. We are looking at Saphira thermal plates. Are you using violet or thermal plates? You had mentioned the Pro-setter, which I believe is the violet plate setter.
Thanks!

 

[csm20]

We us the violet plates.

Fuji vs Saphira (AGFA)

Fuji vs Saphira (AGFA)

The Saphira plates are actually an Agfa plate distributed by Heidelberg. I know of six large shopsin the Southeast and the Midwest that went to the Saphira plates because Heidelberg was offering the package at a very low price. After 6 months or more of fighting with plates not rendering the same dot from plate to plate and even on the same plate due to inconsistent emulsion coating. Sometimes cheaper isn't better if it costs you more for re-runs, re-makes and lost press time.

The only one I can comment on is the saphira thermoplate PN. This is the only plate we've used, we image them on our Suprasetter 105 with a Raptor Pro 85 processor. When comparing them back to back with the Fuji LH-PJ from a print stand point in our press room they were equal. They have some slight difference in print characteristics than the Fuji, our waters went down slightly(only a few%) and we changed our press start up program to drop the waters on one less press revolution. That's it, it was pretty seemless. It almost seems like it's agfa's attempt to copy the LH-PJ. As mentioned before the big thing is to stay on top of the processor maintenance, the plate will NOT perform at all if this is neglected.

I agree cheep is not better, we haven't seen anything like that with the PN in the last year we've been using them. However we never saw anything like that in the 10 years using the LH-PJ either. No denying LH-PJ is a good plate.

I used the Saphira Violet plate for a good 5+ years, and we (prepress & press room) loved the plates.
We ran Fuji's prior to the Saphira, and our pressmen had no complaints when we switched.

 

[Raymond Ramirez]

May I add 2 cents. We are comparing apples to oranges here. Cost and productivity. In my dealings with plates, The fuji thermal plate with the FLH-Z series processor is hard to beat. The processor always seems to be the issue. Fuji has applied the same technologies in to the interplater series
processor for violet interplater hdx.

The thermal chemical requirement set for replacement at 2000 sqm that is over 2000 40inch plates or 60 days between chemical change is a plus. But again the Z series has allowed customers to have a more "Open Window" in turn this can be a downfall because the customer neglects to inspect and clean before startup daily. Remember CTP stands for Clean The Processor

Fuji LP-NV2 switch?

Fuji LP-NV2 switch?

Currently using Saphira violet plates w/Hberg prosetter. Getting pitch from local dealer to switch to Fuji LP-NV2. We would love to get rid of the purple juice and monthly cleaning that takes 3-5 hours.

The pricing looks attractive and the process much cleaner, (ph adjustment vs. silver recovery and 6 filters). We've been told we would be cleaning processor at 6 week intervals and it would take 30-60 minutes and cost of juice about $0.06/sq. ft vs. $0.35.

Would like to hear some pros and cons before testing the plates on press.

Thanks.

I am glad you are asking first before going forth. First thing is first. You have to vertify the laser diode power to the drum to make sure that the diode is not set to 5mw for the silver halide. since the LPNV needs the 60mw to expose the plate. I think this is just an adjustment. Your unit should have a 60mw in it. I can assit you after you verify your laser power. You can email me at [email protected]

 

[marktonk]

If your Prosetter has a 5mw laser, you will need to upgrade to 30 or 60mw.

Have you considered the following:

Do you have room for larger processor?
Do you know how much water this & all photopolymer plates use?
How many more btu's does the processor output? Did you know it has a preheat you do not have now? This is another processing variable. Do you have adequate AC & humidity?
How much more electricity does it use?
What is the plate requirement for humidity & temp? What is the range you need to maintain?

I would ask about these.

Regards,
Mark

 

[Raymond Ramirez]

There are alot of veriables as Mark suggested... There are specific lighting requirements also. (I think you may have this covered)

 

[janezl]

Safelight is not the same. Might need different type of filter. My experience: Saphira violet silver: bright yellow, Fuji LP-NV: dark orange. Had to change filter type.
