Title: High-gloss prints from inkjet printers
Post by: shadowblade on June 09, 2013, 08:17:41 am
Having up till now printed all my photos using a C-type process or on Metal Prnts, primarily for their ultra-high-gloss capability, I have recently gained easy access to a HP z3100 and Canon ipf9000 printer, and it occurred to me that it may be possible to get the same high-gloss effect by printing on an inkjet paper, then laminating it with a high-gloss laminate before mounting on Dibond or a similar substrate, thus getting the glossy effect but with all the advantages of an inkjet print (wider gamut, etc.).

Has anyone done this? How does the gloss compare with, say, Cibachrome or Fujiflex?

Also, what papers would you recommend for lamination? I am after a paper capable of rich, deeply-saturated colours, with a smooth surface (for lamination) and of archival quality (so minimal optical brighteners). Would something like Hahnemuhle Photo Rag, Photo Rag Ultra Smooth or Photo Rag Pearl fit the bill? Or do they lose out too much on the colour saturation?

I can recommend the Ilford »Smooth High Gloss« (215g) paper from their »Galerie Prestige« line. It is the glossiest inkjet paper I have seen so far.

Another very glossy paper is the »Photo HighGloss Premium RC« (315g) by Canson.

You can definitely compare inkjet prints on these papers with chemical prints. The only thing that might disappoint you is the gloss differential on the inkjet prints – traditional chemical prints are more homogeneous in this respect.

If you use one of the papers mentioned above, you don't necessarily have to laminate the prints to achieve a high level of gloss.

Gloss differential, bronzing and lower permanence are the main reasons I'm looking at laminating a matte or satin print rather than printing on glossy. How do these papers perform in that regard? If you put a glossy laminate over a matte print, there's no gloss differential.

I'd be laminating them anyway for protection (from humidity, ozone, etc.), so it's no problem to put down a high-gloss laminate. How glossy can you make a print using laminate?

My favorite glossy look for this format is to laminate metallic paper prints with glossy laminate. It really pops with huge gamut and deep blacks. The right image looks quite 3-D.

All the usual caveats apply...

Don't you get terrible gloss differential with pigment inks on metallic paper? And the fact that the pigments will likely outlast the paper...

No gloss differential once laminated. Look, my laminated prints that are mounted to Gator foam aren't going in the Guggenheim, so the longevity of this arrangement is probably great enough for my needs.

How long do you reckon the paper lasts?

The thing is, some of my shots do end up in galleries, or as long-term displays in hotels, etc., so longevity is kind of important, hence my use of metal prints and Dibond mounting.

Fair enough. But mounting and laminating a print is, just in my mind, contrary to notions of serious art where archival stature is critical. Going back to your comments about longevity: How long do you feel metallic paper pigment prints might last - just a ballpark?

I'm no expert, but maybe 15-25 years before fading beyond acceptable limits?

Also, I'd say that a print made using durable inks on a quality paper, mounted to Dibond and laminated with a protective coating, is pretty damn archival - the Dibond isn't going to warp or disintegrate any time soon, and the combination is a whole lot more durable than the print on its own. It's also just about your only option for frameless display (since acrylic facemounts can outgas and bubble).

Are there any problems with using pressure-sensitive film laminates on non-RC papers? Does it work better on glossy papers, or matte?

Very hard to say. There are no independent tests that show laminated print's longevity numbers. Fading of the inks and paper white shifts (in combination with the glue in contact), color shifts in the lamination film or glue, delamination etc are all possible weaknesses. You mention acrylic facemounts and there are several varieties of that but they also are not tested that thoroughly either and share some aspects with lamination so similar issues you mention above could happen.

What has been tested well so far are glass framed prints with the prints sprayed with a protective coating and without a coating.
Wilhelm-Research, Aardenburg-Imaging.

Then there is the preservation condition that the protection of the print should not make restoration impossible. Whether that restoration is doable at all on inkjet prints is open for discussion but lamination would make things worse.

One would assume that a laminated print would have greater longevity than a non-laminated print...

I've been using the resources at Aardenburg.

The problem with glass is that, for my prints at least, the glass and frame seriously detract from the high-impact nature of the photos. As in, when you look at the high-gloss, frameless version (e.g. metalprints or acrylic facemount), you think, 'Wow!', whereas, if you look at the same print in a frame and behind glass, it's more like, 'Nice photo,' without the same degree of impact.

How good are the protective sprays at stopping moisture, ozone, pollutants, etc.? Can the sprayed surface be easily cleaned? Also, are protective sprays able to impart a high-gloss coating to a print, or are they purely protective?

What about mounting the print on Dibond without a laminate, but with protective spray instead?

Looks interesting - unfortunately, these aren't my printers, merely a lab I have easy/cheap access to, and they've never printed on this paper before, nor do their suppliers stock it.

How much does the glossiness of the underlying paper matter, if you're going to laminate it with a high-gloss laminate? I've heard that it can be difficult to apply film laminates to glossy papers.

I've had a look at some Museo Silver Rag - looks pretty good. Has anyone tried laminating it? It has a slightly textured surface, so I'm just querying how well it would hold a laminate.

Lamination is likely to be a plastic of some kind.  Almost all plastics exhale things as they age, notoriously noticed inside autos in hot climates.   The there's the adhesive between the image and the laminate.

Without proper (Aardenburg) testing I would never tell a client that a laminated print was archival.  (By archival I mean just one component, image fade.)  What does "Frama" think?

Even with liquid laminates? Or is this just a problem with film laminates? These laminates are currently used to seal Fujiflex and Cibachrome prints onto aluminium, so I'd imagine they'd be pretty stable. Won't an uncoated print just absorb moisture from the air and be destroyed that way?

I would have thought that for something to be 'archival' took more than just chemical stability of the dyes into consideration. After all, it's no good if the dyes last 500 years, but the paper disintegrates. It's also no good if the paper warps and bends, or if it absorbs moisture from the air and is spoiled that way.

Just saw an exhibition of Albrecht Dürer prints, none of then under 500 years old, the paper and vellum seems to have stood up very well. But we are talking pigments, not dyes.

Hi,

I have laminated all kinds of papers. The ones that work best are papers like Epson Premium Glossy. In the past I have mounted prints on dibond, wood, glass, ikea wardrobes, treehouse etc. I even created a copy of this famous Zanotta design table (http://www.architonic.com/pmsht/quaderna-zanotta/1002112). Always printed on Epson 9800/7880 and 7900. Lamination is great for these interior design kind of stuff (be it glossy or matt) but for photos on a gallery wall the look is too plastic.

For my own photography I have been using 3 and 4 mm plexiglass instead. Usually I would mount the (premium glossy) prints under plexi and then put them on dibond or even on wooden boxes as can be seen here in this exhibition in my gallery a few years ago (in this 360 image you can see my prints mounted on wood and plexi, the first try of the Zanotta table (turn 180 degrees) and underneath the table you can also see the silicon roll mounting machine I use) The link is here

http://www.360cities.net/nl/image/icipici-jochem-schoneveld-rome#92.10,16.50,80.0

Trick with roll mounting is to go slowly. You will not have any problems with air bubbles in that way. With plexi an antistatic horsehair brush is needed.

Pardon my ignorance, but doesn't an acrylic facemount *also* look like plastic? Or, to put it another way, similar to a perfectly-smooth, highly glossy Cibachrome print? After all, you're essentially mounting it behind a big piece of plastic...

Not that there's anything wrong with that look, of course. I use flush-mounted metal prints for my exhibitions, which have a similar effect to face-mounted acrylic, in that they have a smooth, extremely glossy surface and, in the right lighting, take on a 'glow' that makes them almost appear backlit. My main issue with acrylic facemounts is that they can bubble over time, rendering the entire print worthless.

Have you had any problems with delamination or the laminate changing colour (e.g. turning yellow)? Compared to your acrylic facemounts, how glossy are your laminated prints, especially those made on not-completely-smooth papers (e.g. Hahnemuhle Photo Rag, Photo Rag Pearl or Museo Silver Rag)?

Also, does laminating get rid of any problems with bronzing and gloss differential? If so, I might be more open to the gloss papers - after all, matte papers have the problem that, if you so much as press a finger into them, you'll leave a dent...

I have had mixed results trying to facemount inkjet prints, and currently avoid it.

What keeps me from pursuing it is the logic (where actually logical or not is another discussion) that an inkjet print is paper with a inkjet receptor coat applied and ink sprayed on top of that. My fear is that over time the bonding may actually separate the receptor coat from the paper backing.

As far as the original question, there is currently no pigment inkjet process I have seen that matches the pure gloss of a  Ciba or Flex print.  I believe a dye based inkjet printer may get closer, but I don't have much experience with those.

Fair enough. Is that true of liquid laminates as well, or just film laminates?

Also, on a digital Lambda/Lightjet print, the layer containing the photosensitive emulsion is also separate from the paper - what are your thoughts on a film laminate separating the emulsion layer from the backing paper with those prints?

Even with a glossy laminate layer? I always thought glossiness (or lack thereof) was due to the smoothness or roughness of the microtexture of a surface. Cibachrome and Fujiflex (and Metalprints) are extremely smooth, and thus extremely glossy.

Several texture issues to keep tabs of.
Most papers and over laminates have some form of texture.
When I started laminating I must have run a dozen papers to get the smoothest finish with no texture.
Starting with papers the 2 finalists were Lexjet Metallic and my favorite Pictorico White Film.
Both of these under plexi or a hi gloss laminate are super smooth.
You take a paper like Epsons premium Luster and put it under plexi the texture is magnified.
The next issue if you are using a laminating film is that most of them also have texture.
I use Seal laminates. Print Shield Matte and Print Shield Luster both have a fine texture when laminated over the Pictorico film. You have to go with polyester Print Guard uv Gloss to get a crystal clear finish similar to face mounting with plexi. It is finicky stuff,really need a clean room with anti static tools.
Too much trouble so I do not use it on a regular basis.
I agree with Wayne on face mounting plexi. For me their are just too many issues that do not make it profitable to run.
My cabinetry shop is attached to my printmaking studio and even though we have sealed doors between the buildings sometimes dust has a way of going where we just cannot have dust.

This lab doesn't have Pictorico film or Lexjet Metallic, but does have InkjetPro Professional White Glossy Polyester Film and Moab Slickrock Metallic Pearl, which are of similar appearance.

I wonder about the permanence of prints on Pictorico (or Inkjetpro) polyester film, though - the one test I could find on it showed extremely poor permanence for prints on it. And the Moab paper has high optical brightener content, which I'm generally not too keen on (do optical brighteners have any impact on RC papers anyway?).

Have you tried laminating a smooth matte paper? How does that turn out, in terms of gloss and surface durability. Does the glossy laminate improve the dmax and colour saturation?

I've had the most success face mounting to various thicknesses of Plexi with a 26" Drytac using Epson Premium Gloss 170 and a product called "Schticky" - a silicon lint roller.  It's positively worthless for the uses advertised, but if rinsed between prints, it works better than statically charged Micro Fibre cloth in my dusty workroom.  The 170 is very light and transparent and wall colors will show through it.  It's archival quality is not known to me, but in 7 months I've not seen nor heard complaints about de-lamination or bubbles from out-gassing.

Yes I have laminated over several of Epsons matte papers. The Hot Press and Cold Press lines. I did not try any gloss laminates over them as I was shooting for the low luster matte look.
All of the matte laminates are way too milky and just destroy the clarity.
The best was the the Print shield Luster. More on the glossy side then matte but overall a pretty nice satin look. Surface durability is excellent with an uptick in Dmax.

Sounds good - I guess a glossy laminate would result in an even greater increase in Dmax and colour saturation, then?

What about slightly-textured surfaces, e.g. Platine Rag, Hahnemuhle Photo Rag Pearl or Museo Silver rag? I'd imagine the glossy, slightly-stippled surface would look great underneath a high-gloss laminate, for an almost multilayered effect, but I'm not sure how well a laminate would stick to a surface with even a slight texture.

It's also occured to me - if a paper is resin-coated, i.e. covered in a thin, smooth layer of white plastic, like most metallic papers, does it even matter if the base material has OBAs, if the real 'background' of the photo is the white plastic?

Yes it matters, the RC coating isn't generally UV protective, it it were then the OBAs would have little affect. It depends on where the OBAs are. They are more stable in the paper composition, than in the outer layers.

The application and bonding of the emulsion to photographic papers is substantially stronger, and in fact you can strip the paper backing away with the emulsion in tact. The dyes are embedded into that emulsion, not sitting on top like ink. Much different than inkjet receptor coat/ink (very fragile).

I have no proof or evidence of this being an issue.  However I'm also concerned that the varying depth of the inkjet prints could cause some small lines of bonding issues, it is very difficult to get a perfect seal against acrylic or glass when facemounting and any surface irregularities can be a problem.
