GENERAL

 

Type:

• Dye-based fountain pen ink.

Presentation:

• Bottle.

Availability:

• Available when Topic posted.

Daily writer?

• In the running.

A go-to ink?

• When a pleasant low velocity Blue-Blue-Black seems appropriate.

USE

 

Business:

(From the office of Ms Blue-Black.)

• Suitable for most general business use - going diligently about its duties without distraction.
• I would be reluctant to use PQBlBk for upward communication except at dark value, at which the ink would project greater stability. [Not that those using it at light value are necessarily unstable.]
• Perfectly fine for personal work product: provides a pleasant writing experience on common papers; and a highly readable result.
• Just enough separation from material printed in Black to be used for annotation, marginalia & forms, but not enough zip for concerted editing or mark-up.
• Not nearly enough zap for grading or error correction.

Illustrations / Graphics:

• May be set aside due to the possibility of colour-shift towards Teal and fading over time.
• In the short-term, PQBlBk will do for a general purpose low-chroma Blue, filling the gap between Black and Medium Blue.

Students:

• PQBlBk would have what it takes to be a good all-rounder if only it had a modicum of water resistance.

Personal:

• Hmm . . .
• A bit conflicted, as if it was initiated by under-inspired biro users, but rescued in the nick of time by ink boffins.
• Perfect for pro forma personal business writing when some stealth is called for.
• Not too likely that I'd use it for personal 'personal' writing, other than letters addressed to distant family and/or nearly forgotten acquaintances, especially when one doesn't mind if they don't respond any time soon.
• No particular attention to paper or pen seems to be required - which is an admirable quality - just charge your pen then carry on with an enjoyable writing experience.
• PQBlBk is not the sort of ink that I would be tempted to showcase, rather leave it go about its primary task of conveying what's written to the reader.
• Should one choose to add a bit of character, the use of shaped nibs and/or papers that encourage some shading seem good options; and their use seems quite predictable.

PHYSICAL PERFORMANCE & CHARACTERISTICS

 

Flow Rate:

• Slightly wet.

Nib Dry-out:

• Not noticed.

Start-up:

• Immediate.
• With confidence.

Lubricity:

• Quite pleasant.
• Writing on the toothy or textured papers with narrow nibs was not at all irritating.

Nib Creepies:

• Not seen.

Staining [pen]:

• Not seen after three days.

Clogging:

• Not seen.
• Seems very unlikely.

Bleed- Show-Through:

• Staples: See Figure 7.
• Royal: A bit from the Carene.
• All other pen+paper combos were greenlighted for two-sided use.

Feathering / Wooly Line:

• Not seen on papers used.

Aroma:

• Mildly inky.

Hand oil sensitivity:

• Not seen.

Clean-Up [pen]:

• For recently inked-up pens, the use of a water-based pen cleaning solution with dilute ammonia+surfactant did not release any visible residue after the usual regimen of water flush, short soak, flush.
• Clean-up was very fast, so PQBlBk is one to consider if changing inks on-the-fly and/or to pair with pens that are tedious to cleanse.

Mixing:

• No stated prohibitions.

Archival:

• Specifically denied by Parker.
• Members have previously mentioned fading and colour-shift towards Teal.
• Kindly refer to Figures 10 & 11.

THE LOOK

 

Presence:

• A classic default ink.

Saturation:

• Quite low.
• An effort is required to achieve a fully-inked line.

Shading Potential:

• Moderate, but can be encouraged.
• Pleasant when it appears.

Line quality:

• Impressive through-out.
• Relatively little line-width gain (spread) across the range of papers.

Variability:

• Pen+nib combos used:
  • Quite a bit less than expected, especially for an unsaturated ink.

  [*]Papers used:

  • Less than expected.
  • The hard textured surface of the G Lalo presented no difficulty.

Malleability:

• Modest.
• PQBlBk can be run at a considerable range of values (light - dark) without misbehaving.
• Papers with an off-white base-tint are quite likely to influence the appearance of what's written, but not to a significant extent.

PAPERS

 

Lovely papers:

• Crisp whites.
• Cool whites.

Trip-wire Papers: ☠

• Not seen.
• I would steer clear of dirty whites.

Tinted Papers:

• Very much a matter of personal preference.
• The appearance on warm G Lalo [natural] White has a slight Aqua note, which is fine by me.
• Could be run at a dark value to generate contrast & snap, but may not be sufficiently saturated to retain its native colour on the strongest tints.

Is high-end paper 'worth it'?

• Not particularly.
• PQBlBk showed most of what it has to offer on the penny-a-page HPJ1124, though the Rhodia did encourage shading, so give the coated papers a whirl.

ETC.

 

Majik:

• Impossible.
• Even with the roomy performance envelope that supports significant conjuring, there's just not enough latent energy in the bottle.

Personal Pen & Paper Pick:

• The Platinum President Purist on HPJ1124.
• I like the slightly wide nib that gives a value dark enough to keep what's written well anchored to the page, with just enough shading to distinguish itself as an FP ink.
• HPJ1124 does what it does best: stays in the background, well out of the way.

Yickity Yackity:

• When this ink was reformulated some years ago, I was aghast at the changes to appearance and performance: I thought my two bottles would outlast the footprints on the dark side of the moon. Having recovered from that trauma, I reckon that PQBlBk could be put in any pen and used without grimacing or making a grumpy face. Indeed, one could do far worse.
• Ah kushbaby, have you the need of a default ink that is not Zombie resistant?

Other Inks

◊ This Review uses the same Written Sample format, atrocious handwriting and some pen+paper combos common to most of my previous Reviews of both Blue and Blue-Black inks. Consequently, ad hoc comparisons through manipulation of browser windows is supported.

◊ Should that functionality not meet your requirements, I welcome your PM requesting a specific comparison. Additional scans may be produced, but the likelihood of additional inky work is quite low.

 

Fine Print

◊ The accuracy and relevance of this Review depends in great part upon consistency and reliability of matériel used.

◊ Ink does not require a label/notice to indicate (changes in) formulation, non-hazardous ingredients, batch ID, date of manufacture, etc.

◊ As always YMMV, due to differences in materials, manner of working, environment, solar flares, etc.

◊ Also, I entrust readers to separate opinion from fact; to evaluate inferences and conclusions as to their merit; and to be amused by whatever tickles your fancy.

Informative as ever and a good review of one of the first inks I used after the obligatory Washable Blue. I still don't like the Teal final colouration but it's definitely a good all-rounder and I'll try the old 'drops of red' experimentation to get rid of the 'duck syndrome' at some point.

Hi,

 

Glad you liked the Review.

 

I kept delaying running this ink through the review process for quite some time - until I thought I could approach it with 'fresh eyes', to see the ink for what it is. I face the same challenge when looking at inks such as Waterman Serenity, Lamy Blue, etc.

 

As ever, I think the Written Samples speak with the loudest voice.

 

The 'duck' [Teal] aspect doesn't strike me as being all that strong. That said, I tend to prefer Blue-Black inks with more of an Indigo hue, which a whisper of Red might achieve. Ignoring Parker's colour designation, I consider PQBlBk a low chroma Blue, more akin to Pilot Blue-Black, not a 'classic' Blue-Black in the manner of Pelikan 4001 Blue-Black. (Hair splitting?) Both of which I consider all-rounders.

Pilot Blue-Black: My Review

Well, you know my thoughts on 4001...!

And I wish I could get the Pilot Blue-Black in bottles. Their Blue is just a bit pale in my Fine 823 which I've recently bought.

Just for your info, the Cult Pens/Diamine Deep Blue Black is a very pleasant wet ink and it really helps that oh-so-fine F on the 823.

 

 

[mAnuscript69]

Great review, as always

 

My sentiments towards Quink Blue Black are perpetually shifting between like it and loathe it.

I find that the colour shift towards teal is more apparent on copy paper or cheap paper which I'm guessing has a high acidity content. Also, the teal hues are not as strong when used in a wet pen; it is quite pleasing to my eyes. From a dry pen, it is most definitely green.

 

I like using this ink for pen testing and ephemera but only in wet, broad nibs. Unfortunately the ink fades quite prominently and as such I don't use it for long-term notes.

[cellmatrix]

Great review! I always learn a lot from these.I think that the shading you show is pleasant and I like the teal when it appears. So many people have commented on Waterman Mysterious blue and Parker Quink Blue Black having so many similarities or being the same product. But having just switched from parker blue black to Tsuki-yo in my fairly wet parker 45, I can't help but notice some similarities between these inks too. Parker Quink blue black certainly seems a bit less vivid/more faded appearing and its totally non water resistant compared to Tsuki yo, but to me the overall hue spectrum, tendency for shading and good ink flow/lubrication are similar with these two inks.

Edited April 20, 2013 by cellmatrix

[ShinyDemon]

Very interesting. To me that's just "blue".

I used to have a bottle of superchrome blue-black from the 60s and it was epic stuff. Very dark with bronzing. It's a shame they don't make it like that any more.

I'll have to stick with MB Midnight Blue, but even that is a poor sub.

[wastelanded]

This ink remains an enigma to me. After the initial shock of it not being a typical blue-black, I began to explore it for what it is. It's not blue-black, it's not a 'blue', it's not quite a teal. The colour shift seems to vary wildly depending on what paper is used, I imagine something to do with the pH of the paper. On some papers I've tried there's barely any shift at all, on others it turns quite greenish. It's still a surprise ink at this stage. I think if one could dial it in on a variety of papers and be familiar with the results, PQBlBl could be a pretty useful multi-purpose ink.

 

I agree with Cellmatrix above, there is indeed a similarity to Tsuki-yo. It doesn't have Tsuki-yo's depth or ability to shade but it's close in the spectrum, something akin to the similarity between Tsuyu-kusa and Diamine China Blue.

 

Excellent work as always, Ms. S1, I've been waiting for you to do this one.

What is Trip-Wire paper?

 

Trip-wire papers are ones that might not give you the best results with the ink in question.

[dcwaites]

Ahh, memories...

 

High School was written in PQ Permanent Blue-Black w/Solv-X. When I went to Uni, I upgraded to PQ Perm. Black.

 

A few years ago when I returned to the FP fold, I bought a bottle of the new, improved PQ Perm. Blue-Black sans Solv-X, complete with new colour. Most of it is still in the bottle.

 

I was able to buy 5 untouched bottles of PQ Perm Blue-Black w/Solv-X, and this is what I use to rescue sluggish pens. A few days of writing and the Solv-X actually seems to do what it is advertised -- Cleans the pen and makes it write as new.

 

However, I have just come across a sample of both new and old Blue-Black on some cheap paper a few years ago. Both are now a lovely shade of greeny-blue...

 

BTW, lovely review, as usual, Sandy

Hi,

 

Thanks!

 

I appreciate your sharing your experience with this ink, especially as it is so variable.

 

The Review includes two comparisons of the change of appearance over time, both of which are on acid-free paper. As they do not show a marked change, I think you are right in that the paper is likely the major factor influencing fading and colour shift.

 

I stumbled across a USA Library of Congress document from 2012 that gives a brief & clear insight into paper deterioration, including the increase of acidity over time in some types of paper. LINK

 

I suggest that anyone who notices deterioration of important records undertake a media conversion project to avoid loss of information, which the availability of low cost digital cameras puts within range of many people.

Hi,

 

Thanks for the compliment!

 

I am always glad when readers learn something from these Reviews.

 

Thanks also for sharing your experience with Pilot tsuki-yo. I use that ink more often than PQBlBk, and have found that it offers a far greater range than PQBlBk. Pt-y has that 'certain something' that earned it a spot on my top shelf. However, I do take the time to select the pen+paper combo to get just the right appearance, which I would be less likely to do with PQBlBk.

Waterman Mysterious Blue (ex-Blue-Black): My Review

[mAnuscript69]

...

The Review includes two comparisons of the change of appearance over time, both of which are on acid-free paper. As they do not show a marked change, I think you are right in that the paper is likely the major factor influencing fading and colour shift.

...

I'd like to add that my experience with PQBlBk on Rhodia is very different from yours. Perhaps it could have something to do with humidity, as I live in the tropics - my writing on Rhodia paper does shift to teal eventually though not as fast and significant as on copier paper. The end result is usually reached within a couple of days.

 

If it's worth noting, my bottle is about a year old.

 

Post Script:

I'll do a writing sample one day apart and scan them over the course of the week. Will post the results when the final colour is achieved.

Hi,

 

Well, I must say that we have somewhat different ideas about the colour Blue - I consider PQBlBk to be a low-chroma Blue.

 

I have some notion of where the imaginary boundaries between colour groups might be placed, but I leave the naming to each person. (My conflicts & contradictions regarding Blue-Turquoise-Cyan naming is well known & thoroughly documented.)

 

Every so often I need to take a look at my colour wheel to 'caibrate' my eyes, so here we have it:

http://i783.photobucket.com/albums/yy116/Sandy1-1/FPN%20Stuff%20-%202011/186ecf6a.jpg

 

That Superchrome Blue-Black must have been astounding stuff for the exquisite MB Midnight Blue to be considered a "poor sub".

Hi,

 

Thanks for your kind words!

 

I don't think this Review shows anything too terribly new / exciting, but its time had come to get ticked-off my bottomless To Do list.

 

Once again, I didn't find colour variation in the near term, nor the gradual colour shift (migration) over time. I like to think that being from Parker, (Rubbermaid), there's pretty good quality control / assurance, much the same as Waterman inks and other 'global' marques, so that would tend to rule-out variation on a bottle-to-bottle basis. That said, Waterman BlBk is also reported to have stability issues; and Pelikan 4001 BlBk occasionally deals a Joker.

 

As always, I welcome dear readers to share their experience, and contribute their examples to this thread.
