Hi ! Pasos,

If I get you correctly, You mean that within a sheet, you will see different color in terms of L* A* B* Delta E* or OD ? How big is the different?

Regards

It might have to do with the RIP in some part, but it also has to do with the printable color gamut of the machine, density range, and simple resolution. It still doesn't have the range of shadow density of an 8- or 12- color inkjet for example, but the range of dark grays before they become black seems better than any laser I've seen to date. I was also impressed with the resolution - blades of winter/spring grass had a nice degree of individual sharpness and shadow detail without becoming either cartoonish (from the application of the black) or all blending together in one textured tan mass as other lasers tend to do.

How about grey tone page? Is it very uniform? Cos most of the digital offset have problems on this grey page.
Acceptable, but not perfectly consistent. The 25% gray was very consistent, but the 50% gray showed some slight streaking - to my eye it appeared to be drum wear as the inconsistency was in the 18" direction not the 12" direction. How much would it cost to maintain the machine to a higher specification to not have this - I don't know. I don't think it would affect photographs at all though.

Do u know whether is there a problem running through hot OPP lamination?
What temperature does the hot lamination run at? Easiest might be to get a print sample and try it to see if any affect on the toner is detectable.

May I ask what machine you are using to hot laminate? I was wondering if there was a machine that could load a stack of 1,000 to 1,500 prints, laminate, and cut them as a way to gloss over toner on uncoated paper. I have not seen such a machine to date.

How much is 4 color A3 size print in the market?
That's a good question too - I do not know how the price per print compares right now to what can be delivered on the previous generation CLC for example.

4 color will only create 4 color gamut - but is good enough for my application - normal photos. How big is the gamut depends on the pri and secondary pigment (L*A*B*) in the manufacturing process. Optical density range is only part of the printable gamut. By the way, paper also play a very important parts of the color. Reason is that the ink is just a few micron on the paper. Fedrigoni is a good but expensive paper for photo application. By the way, for normal photo, we don't use to the extreme color. To me, the half tone is more critical.

You are right that as long as the machine defect is not too much, for photo application, slight streaking or banding will not effect the printout too much. I came across some digital machin has very bad banding at the end of the A3 page. Only way to send for the print is to select darker color at the end of the page so that the banding is not obvious. Thus, at the end, I decided to reduce the print size of my album.

What temperature does the hot lamination run at? Easiest might be to get a print sample and try it to see if any affect on the toner is detectable.

OPP lamination only runs at 80 to 90 degC. And polyester laminate runs at 110 to 120 degC.

May I ask what machine you are using to hot laminate? I was wondering if there was a machine that could load a stack of 1,000 to 1,500 prints, laminate, and cut them as a way to gloss over toner on uncoated paper. I have not seen such a machine to date.
Checkout GMP from Korea


That's a good question too - I do not know how the price per print compares right now to what can be delivered on the previous generation CLC for example.
Any limitation on substrate? Gloss coated, Coated matte and Uncoated? Does the substrate needs to be approved in order to be used?

Possible to send me some printout? Can I contact your profile directly?

Andy

I'm a canon user (but not an imagepress user yet) not an equipment dealer -- for print samples from your files contact IKON if you're in the US -- http://www.colorprintingforum.com/ca...7.html#post283 (Canon imagePRESS C1 print samples?)

May want to switch from photolab to digital press printout - cheaper in cost.

How is the print quality?
How is the Handling/scratch resistant?
How is Canon image press on Hot laminating?

Print quality on the imagePRESS c1 is second to none, great for photobooks. It is scratch resistant, better than the iGen, HP indigo (worst for this), and it laminates, and can be UV coated perfectly!

Default Canon imagepress quailty vs other digital presses

Recently looked at three machines Canon C7000vp, xerox 5000, and
Konica Minolta 6500. Their are many factors to get the color you are looking for mainly how the file was prepared and the rip that runs the machine. I took several of my files and made press quality pdf's converted all colors to cymk using swop coated2 profile. Now when they printed off my files from a fiery rip using canons profile I found the prints to be dark, they said because the machine has such a large color gamut, when you use say my swop profile the color gamut is smaller. I don't care what the gamut is I just want my files to look right. Now when I printed of the Konica Minolta they had trouble with one of my files with transparencies using a Creo rip. They switched to a Fiery and used my swop setting in the rip and bang looked very close to what I ran on press (very pleased) Xerox demo sorry to say did not go well tech didn't show up salesmen tried to do demo, had troubles with machine so I can not give a good evaluation. I'm sure if you set your files up and use the right settings such as the swop I used the Canon could have done very pleasing color. They did do prints of some of their files and they where very nice. They
have just completed and Independent Technical Evaluation of several digital press vs a 40" Heidelberg and what I read out of GraphicArts magazine sounds like they faired very well. They have a report you can buy at www.ipa.org/digitalprint have not purchased it yet myself. One last thing I brought some of my stock to these demos. One was a Hammermill color copy cover it is a non-gloss sheet and the prints that came off the canon had a shiny look to it didn't like how that looked. Depends on what you want but the price difference between the Canon and the Konica Minolta machine is huge but from what I seen in the prints very little difference is it worth the money?
