one topic, one word world.

the snobby hobby.

One word diagnosis, as though “he died of temperature” offers a pathway to knowledge of medicine.
Porous, like crossover, isn’t enough of an answer. It settles the matter; it also stops inquiry into what the actual mechanism is, the controllable ones.


alecrmyers [I don't recognize the paper I'm using as specifically being microporous. (his question about “pinholes” {which are likely fisheyes}

It is. Inkjet papers need to soak up ink, so a plain PE layer without any holes in it wouldn't work. The ink would puddle and smear.][first answer that comes to mind]

[my answer]inkjet receivers can be made using microporous coating, swellable polymer coating, matte coated. Canon, HP and Kodak provide swellable polymer and microporous coated. Epson is most often microporous. Kodak has commercialized a wider range of coating methods.[this was as of 2002]

I am resisting showing the patents — think of it as an exercise for the interested.

Ortho — true color … not all ortho films are the same… they don’t produce the same image look; range, response to scene color and brightness.

when people arrive with more foundation than the reviewer, the advice may be less useful, even a distractor. worth saying that the high posters frequently are less depth than the questioner, the seeker. google brings em to the slaughter house -- a matter of ez-pass, aka, path dependency.

RC remains disliked by the freezer set, even as they use RA4 paper, forgetting that resin coating was  arrived as a color print paper. Fiber paper left color printing, being replaced fully in less than 2 years. Oh, color paper, RC paper can be mounted to paper, cloth, metal, plastic... even concrete.. depends on how much you know, which depends upon how you imagine.
[Resin-coated materials were introduced for colour emulsions in 1968 and black-and-white emulsions approximately four years later.]

as a thread gains technical input, THEY must switch. now, they are an artist basing an opinion on ... that other stuff, even though they remain an invisible actor in a forgotten tributary of exhibition-collector world.

curtain coating (or slot die coating) 

Coatings can be horizontal or vertical, it is the nature of the head end or "hopper" that determines the "modernity" of a coater as follows:

- Trough coater
- Trough with doctor blade or air knife
- Extrusion hopper
- Slide hopper
- Curtain coater

suppose you had a lab

“I find it puzzling that the dye transfer aficionados like Ctein hung up their spurs and no longer offer new prints, other than what exist from old stock they had hoarded.”

Suppose an established photographer came to you requesting $200K worth of work but you had just closed your darkroom. Meaning, you had taken the plastic sheets down in your garage basement; taken the spray hoses off the tub sink; folded, discarded the collapsable party tables. Even had packed away lenses and enlarger, making them ready for shipment or sale to people of the forumatti.

Would you turn down the request saying: “I’ve just closed my darkroom, sorry.”

Credible. Edible test time. Or do you just swallow cause it is told you by the big name dropper himself.

What is it that you don’t know. Perhaps the one-name small practitioner knew he wasn’t up to the task. His way of working wouldn’t satisfy the need of the Big Name photographer. And name-drop didn’t have the where·with·all to build a proper lab set. 

He had no way of knowing that it would take: $10K + $60K + $8K to get that toll coater to make the appropriate run of mat film. One name, also, just didn’t have the chops to make the prints. He will tell you others don’t make prints as good as his, but why then are all his prints of Rock concerts or rockets. Mostly his own work. 

It is best that he turned the request down, (if it actually occurred) since the lab that took the work is now firmly established and doing well. Well enough that they are working with project schedules more than a year away.
