Disclaimer first: This test does not focus on fading under direct sun or UV exposure, it focuses on normal change in color that will be observed on these inks in what I assume is how most keep their work. Also I will try to keep things as consistent as I can but some variations may occur during the span of testing. I will try to update on any key variations other then weather outside. Storing and approach taken (inputs appreciated) The way the pages will be kept will be as follows : the pages will be kept in closed notebooks and will be used from time to time to see or check for color or such changes, the notebooks themselves will be kept outside the wardrobe in a well lit room. The works will mostly be closed for the test period otherwise. The results will be posted every month to see the change on all papers, point being to observe if page type will lead to any significant change. Any new ideas for the keeping of pages and such are welcomed and appreciated as it is long term test. Introduction and Idea The idea comes from general fading of IG inks and the way it becomes worry for obvious reasons. The subjects under analysis are KWZ IG Blue-black (the ink also is subject to more thorough analysis in other test, pls refer to ink review for that one) and other being R&K Salix as said in intro. The R&K Salix is not being analyzed the same way here as KWZ IG mostly due to net result being known, but the inks performance variation on different papers is not known so the test still serves some purpose (for me at least). Now the net result will also be published and matched along with other test result if someone wants to see them, else not much point as inks analysis is being done anyway. inks nature ( a personal take here on how each write) KWZ IG blue-black - A wet ink in all sense, minor bleed on cheap papers and no feathering seen. Very high water resistance. R&K Salix - Dry ink. Flow sees no issues, no hard starts or skipping seen during writing despite being dry ink. Works on all papers and shows no bleed or feathering on any paper. Pretty much water proof and sees no sign of even discoloring. Krishna Paakezah - Balanced flow ink, no skips or hard starts seen, no bleed or feathering on normal papers. Waterman Serenity blue - Balanced flow ink, no skips, hard starts. no bleed or feathering on normal papers. Some have noted bleed on very cheap papers and that is the case. Pilot Iroshizuku Shin-kai - Balanced flow, tending to wet. No bleed or feathering on papers. No skips or hard starts. The ink shows some feedback of nib and gives pencil like effect in nibs I tested, its very nice feeling when writing. Pens used the pens in order from left to right along with their respective characteristics rough idea Platinum preppy 'fine nib' - Writes dry, no skips and such just dry (some tuning was done to get such result thus statement of tuned in writing). Ink here is KWZ IG blue-black. Wality 69 EB Fine nib- Writes balanced and is and ED pen. Ink here is Krishna Paakezah. Oliver Exam demonstrator, Kanwrite FIne nib - writes wet. Ink used is R&K Salix. Camlin Trinity Fine nib- Feed modded for very wet flow. Ink used is KWZ IG Blue-black Ranga Slim Bamboo, Ranga Fine nib- 3in 1 using convertor in this test. Writes Balanced with tending to wet. Ink used is Pilot Iroshizuku shin-kai. Kanwrite Heritage, Fine Flex nib- Piston filler. Writes wet. Ink used in Waterman Serenity Blue. Intent behind using a dry and wet pen for KWZ ink is to create some level field for testing as direct comparison R&K Salix runs dry even on wettest of pens, the test aims to see what happens if ink on paper is reduced by significant margin and what happens if a wet ink is given a very wet pen, and if same ink is given dry pen. R&K Salix, being a dry ink as it is, I feel will yield poor result on dry pens in terms of ink quantity on dry nibs, I have not tested the ink on dry nibs and I won't either as chances of poor results in long term testing are feared, making idea of aging redundant. Papers used (and their respective nature) From poorest performing paper to best (pages from Nightingale are in no particular order as they all are good in their own way, my ranking thus comes from my requirement of no bleed or ghosting as top priority over other characteristics) I have or will add withing span of a week. Also companies are good at marketing and skipping important details.....that is to say they in many have not given GSM of notebooks 😠 I will approx for those pages, from what I know about them, corrections are welcome. Classmate copy register (50 approx GSM)- not FP friendly paper, highly absorbent nature, no sheen or shading seen here....this was really a disappointment considering all the marketing they do.... Taj White copy register (approx 60 GSM) - OK paper for FP for normal use only. Absorbent in nature, sheen and shade is minimal to absent. Nightingale 70 GSM- FP friendly to some extent, its quite smooth to write on, in a way that half decent inks don't bleed here. Absorbent paper and shows, low shading seen and sheen is seen but not much. 75GSM A4 spectra (office paper in all honesty) - OKish for ink pens...I guess. Bleed and feathering is not seen for normal inks. Absorbent paper by nature. Sheen is seen, not too high but present and Shade is low....(the result will be added in 2 days or so...I need to buy them, my bundle is finished so will add them later). Results added. Navneet youva (approx 60 GSM)- This one surprised me to some extent as I did not expected it to behave properly. Ranks higher for not showing bleed or ghosting on most inks. Still absorbent nature. Sheen is not seen, shade is minimum. It could be near 70 GSM by thickness of paper...they don't mention it so will give benefit of doubt. JK Cedar 100 GSM - FP friendly paper to good extent here. No bleed or feathering on any inks I have tested so far. Not too absorbent in nature. Sheen and shade are visible nicely. Its also my personal standard testing and using paper. Most I have are non standard papers so I apologies for that, thus is the reason for adding this section in particular. If anyone cares among these pages for daily, my recommendation is to go with higher GSM pages of nightingale or Classmate if wanting one of them, the option is there one has to look for it. Test itself All tests in this post are 5 min dry except for JK Cedar which was given 2 hrs to dry. All images are done with pea shooter camera and corrected to as close as possible. Images are quite close to real, not exactly same but close. 50 GSM Classmate copy test, dry time 5 min. pic taken on 7 jan 2021. Taj White 60 GSM approx paper. 5 min dry time. Pic taken on 7 jan 2021 Nightingale 70 GSM paper, dry time 5 min. Pic taken on 7 jan 2021. Navneet youva, 60 GSM approx, could be 70 GSM. dry time 5 min, Pic taken on 8 jan 2021 75 GSM Spectra copy paper. Dry time 5 min. Sheen is visible here, not too much but visible nonetheless for shading its still low. Black lines are Platinum carbon black. JK Cedar 100 GSM. dry time 2 hrs. Pic taken on 7 Jan 2021. Some Niccolo Machiavelli quotes just for fun of it and give some idea of writing (i know my writing is not good but its improving I promise...its now readable from whatever it was before 😅) Whats next and my limitations Apart from office page which I will add this week. I plan to write some more pages with both ink on JK cedar and keep them the same way I am testing if someone is interested I will do them, else not much of personal interest. I have never done a swatch sample before but I want to ask if I should add one for at least R&K Salix and KWZ IG Blue-black.....I probably wont do that for others, too much of personal hassle, but 2 main IG should be fine. Do tell if interested. My limitations are quite obvious, I lack any other nib variation apart from fine nibs and EF nibs so thats one main down. Second is lack of most common FP papers used like tomoe, Rhodia,etc. They are not economical here for me at least and I write a lot so I never bought them personally, I did have some in past but all are used now. Thank you for sticking with this one.
