Black Ink Type

Black ink type and black ink switching when moving from matte to luster and gloss papers – here’s my thoughts on this, initially triggered by Franks’ reply to my previous article HERE.

And I quote:

Another great and instructive article Andy. I have the r3000 but get slightly annoyed with the black ink changes from one to the other. Some further guidance on the use of these re paper ‘types’ would be appreciated by moi ~ please ♡

Look, he’s even put a heart in there – bless you Frank, that’s more than I’ve got out of ‘her indoors’ for years!

Now the basic school of thought over this switching of black ink type is this:

  • PK, or Photo Black ink type supposedly produces a smooth, highly glossy black.
  • MK or Matte Black ink type produces a dull, flat black.
  • Using a matte finish paper requires the MATTE black ink type.
  • Using Luster or Gloss paper requires the Photo black ink type.

The PK black ink type really only produces a HIGH GLOSS finish when chucked onto HIGH GLOSS media.  Its’ got a rather less glossy and more ‘egg shell’ finish when used on a more luster finish paper. There does come a “tipping point” though where it will look a little shinier than the finish of the paper – and it’s this tipping point where theory, clever-dicks and user-guides tell you there’s a need to switch to the matte black ink type.

The Matte black ink type does exactly what point two says it does.

The third point – replace the word “requires” with the phrase “can cope with” and we’d be about right.

The forth point is absolutely true; get this wrong by printing with the MK black ink type on high gloss paper and you’ll just waste consumables and potentially end up with the type of clean up operation normally the preserve of Exon & BP. Dot gain on steroids!

There’s also an argument that the MK black ink type produces a deeper black on matte finish paper than the PK black ink type – this is also true:

Permajet canned profiles for Museum paper on the Epson 4800 printer using PK and MK black ink types.

As we can clearly see, the Matte black ink type does indeed accommodate a deeper black point than its counterpart Photo black ink type.

Adopting the Common Sense Approach

There are a few things we need to think about here, and the first one is my constant mantra that the choice of paper is governed by the “overall look, feel and atmosphere of the finished image” when it’s sitting there on your monitor.

Paper choice IS the final part of the creative process; for all the reasons I’ve mentioned in past blog posts.

You will also know by now that in my world there is little room for high gloss paper – it’s a total pain the bum because of its highly reflective surface; but that same surface can allow you to print the very finest of details.

But here’s common sense point number 1 – the majority of people reading this blog, attending my workshops and coming to me for 1to1 tuition CAN NOT produce images with detail fine enough to warrant this single benefit of high gloss paper.

That’s not because they’re daft or rubbish at processing either – it’s simply due to the fact that they shoot 35mm format dSLR, not £30K medium format.  The sensors we commonly use can’t record enough ultra fine detail.  There’s a really good comparison between the Nikon D800 and an IQ160 here, it’s well worth having a look – then you’ll see what I’m on about.

The point I’m trying to make is this; print on gloss from 35mm if you like; but you are saddling yourself with its problems but not truthfully getting any of the benefit – but you can kid yourself if you like!

I Lust After Luster Papers But How Lusty Is That Luster?

As I mentioned in the previous post, Calumet Brilliant Museum Satin Matte Natural is NOT a matte finish paper.

True matte papers never really hold much appeal for me if I’m honest, because they are very dull, flat and relatively lifeless.  Yes, a 12×12 inch monochromatic image might look stunning, especially hanging in an area where reflections might prove difficult for any other print surface.

But that same image printed 8 foot square might well “kill’ any room you hang it in, just because it’s so dull and so damned BIG.

True matte papers do have their uses that’s for sure, but in the main you need to discriminate between matte and what I call matte “effect”.

Permajet Fine Art Museum 310, Matte Plus and Portrait 300 are papers that spring to mind as falling into this matte effect category – and wouldn’t you know it, there are canned profiles for these papers for both PK and MK black ink type ink sets, as you can see from the image earlier in the post.

So, with regard to black ink type switching you have to ask yourself:

  • Am I using a paper the ACTUALLY NEEDS the MK black ink type?  Chances are you’re probably not!
  • If I am, do I really want to – how big a print am I doing?

In my own print portfolio I only have two images that benefit from being printed on a “dead” media surface, and they are both printed to Permajet Museum using the PK black ink type.

I had another one that looked “nearly there” but the heavy texture of the paper detracted from the image, so it was re-proofed and printed to Matt Plus, again using PK ink. It looked just the same from a colour/luminance stand point, but worse from a ‘style’ point because of the zero texture.

Along comes Calumet Museum Satin Matte Natural!

The subtle texture gets me where I wanted to be on that score, and that ever-so-soft luster just makes the colours come to life that tiny bit more, giving me a print variation that I love and hadn’t even envisaged at the time I did the original print.

Ink Type Switching

I have to say at the outset that I do NOT own an R3000 printer – I use wide format Epson printers and so have no commercial need for the 3000 DT format.  But I always advise people looking for a printer to buy one – it’s a stunning machine that punches well above it’s weight based on price point.

My Epson wide format does not hold both black ink types.  Switching entails a rather tedious and highly wasteful process; which I have neither desire or need to embark upon.

But if you have any brand of printer that carries both types on board then I’d highly recommend you to set the black ink type to PK, and turn any auto-switching OFF – that is, set switching to manual.

Right, now the super-pessimist in me shines through!

I’m not a fan of Epson papers on the whole, and there’s a lot more choice and far better quality available from third party suppliers ranging from Photospeed to Hahnemuhle, Canson, Red River and all points in between.

Now third party suppliers in the main will tell you to use one black ink type or the other – or either, and give you the correct media settings (Brilliant – are you reading this??).

But, if you have auto switching enabled, and use Epson paper, the print head sees the paper surface and automatically switches the ink to the ‘supposed’ correct type.  This switching process requires the printer to purge the black ink line and refill it with the ‘correct’ black ink type before printing commences.

Now these figures are the stats quoted from Epson:

Black ink conversion times:

  • Matte to Photo Black approx. 3 min. 30 sec
  • Photo to Matte Black approx. 2 min. sec

Ink used during conversion:

  • Matte to Photo Black approx. 3 ml
  • Photo to Matte Black approx. 1 ml

Now why the times and volumes aren’t the same in both directions is a bit of a mystery to me and doesn’t make sense.  But what is killer is that the carts are only 26 (25.9)ml and around £24 each, so 6 changes of black ink type is going to burn through as good as £25 of ink – and that’s without doing any bloody printing!!!

When ever I demo this printer at a workshop I never use Epson paper, auto switching is OFF and I never get a head sensor warning to tell me to switch ink even if I load Permajet Museum – the head sensor doesn’t warn me about the fact that I’m using PK ink.

Yes the printer could be up the spout, but using a canned PK profile the resulting print would tend to indicate otherwise.

Or something slightly more dark and sinister might be happening – or rather NOT, because I’m not using OEM paper………...What was that I heard you say?  Good gracious me…you might think that but I couldn’t possibly comment!

One thing to bare in mind is this.  For the most part, the majority of print media will work exceptionally well with the PK black ink type – BUT NOT THE OTHER WAY AROUND – you’ve been warned.  If you want to know how the captain of the Exon Valdez felt and be up to your ass in black stuff then go ahead and give it a try, but don’t send the cleaning bills to me!

I did it once years ago with an HP printer – I can still see matte black ink tide marks on the skirting board in my office……it wasn’t pretty! And it screwed the printer up totally.

Using PK on matte media will only effect the D-max and lower the overall contrast a wee bit; unless it’s a very low key image with vast areas of blackish tones in it then for the most part you’d perhaps struggle to notice it.  Sometimes you might even find that the drop in contrast even works to your advantage.

But don’t forget, you might not be using a matte media at all, even though it visually looks like it and says the word matte in the paper name.  If the paper manufacturer supplies a PK and an MK profile for the same paper then save yourself time and money and use the PK profile to soft-proof to AND to control the printer colour management.

  1. LOLs… Well… yet again Andy you come up with the ‘goods’ to my request for further guidance re the PK & MK ink types… and I’ll be delving deeper in to the printer settings in respect of the “Auto Switching” you mention. I get a message about ‘switching’ but it doesn’t just go ahead and do it – so (without having checked before responding to your info) I’m guessing that means it is set to “OFF” as it’s telling me to “CONFIRM” the switch? No doubt I’ll see when I check the settings!

    Let me say now that I do NOT have – or use – any MATTE paper at this time… although I am considering trying the Epson Double-sided Matte paper – – – don’t ask why… I’m just “considering”!

    All the papers I have ‘at this time’ are gloss types; (Epson) Photo paper, Premium Glossy & A3+ Premium Semi-Glossy. I was also given some Kodak ULTRA Premium and some HP ‘Every day” Gloss photo papers. The print quality appears GOOD/OK/Pleasing but then I haven’t got access to a lot of others to make comparisons with!

    NOW… if “samples” of the papers you mention were available in VERY small quantities – like a couple of pages – rather than in packs I may be tempted sooner. As these are what I have “at the moment” I’m a bit too tight to get rid of and replace with any of the others you mention “at the moment” – but will in time 😉

    So… my point in mentioning the papers I have IN RELATION to your reply is to ask the rhetorical Q. : Why is the printer wanting to change from one black ink type to the other when I am NOT changing from gloss to matte? Does the Epson R3000 see ‘photo paper’ as matte – even though the packaging and visual look of it is gloss! Just ‘chatting out loud’.

    Delving deeper, and with the information you have supplied, I will no doubt come to the solution. It IS a great printer and you saying it’s one you recommend is reassuring. Just now need to start looking at other photo paper choices. Cheers Andy 🙂

    Oh… the ♡…. that was because I was replying on my tablet and didn’t have any smiley faces I could use. You and me both then for our respective ‘her in doors’

    • Franky Baby – I’d like to think the head is sensing any matte paper. But as I said, I’ve sort of semi-proved to myself that it doesn’t.

      But then again, like I said, the printer could be up the spout; though I doubt it!

      Some might think that there’s a “secret code” in Epson papers that triggers the switch.

      Some might think that this switch is prompted unnecessarily just to make the user consume more ink in certain cases.

      But again, as I said before,,,,,,,,,,,,you might think that BUT I COULDN’T POSSIBLY COMMENT.

      If I was you Frank I’d just dump the OEM papers and go for something like Perm Oyster and used the canned PK ink profile for the time being – I think you’ll have less hassle and better overall results.

      In the near future I should have tied down which Calumet paper from their Supreme range would make the best PermOyster clone!

      • Much appreciate your time to give some more feed back Andy 🙂

        I will take your advice… and wait ‘patiently’ for your results on the Calumet papers and act on the results 🙂
