Offtopic: Question on QuadToneProfiler_QuickCurve-DN ver 3+ by Richard Boutwell

Bob Hartung All Messages By This Member #19419 开云体育 If anyone out there is using the newest version of QuadToneProfiler-QuickCurve DN (version 3.1.3) by Richard Boutwell? ? I am wondering exactly where you are supposed to enter the Blocking Density from the blocking density test.? His instructions gloss over specifics.? In my case I can up with a blocking density of 35 (see attached screen capture). I am applying the Blocking Density number by manipulating the "Total Ink Load" slider on the Starter Curve Setup page as on the attached screenshot.? This worked for me, but I am not precisely sure if this was the planned use.? Another individual told me to use 100-(Blocking Density) as goal for the "Maximum Black Percentage"? which threw me way off course.

Criss Hartzell All Messages By This Member #19420 Yes, this confused me too. I made several curves for Pd/Pt and carbon by changing the total ink load to correspond to my blocking density. They worked ok, but, I noticed I was getting star wheel?marks (P900) especially in my negatives for carbon (K45). I decided this was because the ink load was too heavy. When I re-did the curves by making black boost equal the blocking?density, the overall ink on the paper seemed to be considerably less and the star wheel marks disappeared. Also, the linearization was much better. Also, changing the black boost appears to replicate more closely the workflow?in QCDN version 2. I do not have extensive experience with linearization, but that is my recent observation.? toggle quoted message Show quoted text On Mon, Feb 17, 2025 at 10:47?AM Bob Hartung via <rwhart3675=[email protected]> wrote: If anyone out there is using the newest version of QuadToneProfiler-QuickCurve DN (version 3.1.3) by Richard Boutwell? ?

Bob Hartung All Messages By This Member #19421 开云体育 Criss Hartzell, When I switched to this method my linearization was very quick and when scanning the 51 step step-wedge with my i1 Pro I ended up exactly following the green line in the linearization. I have emailed Richard twice about this, but so far no reply.? Perhaps he will answer here.

Lo?c All Messages By This Member #19423 Edited Hi ! ? Please find attached an email conversation (as a PDF file) I recently had with Richard Boutwell about the latest version of his software. I think you'll find answers to your questions in this email thread. ? Overall, I have to say I am disappointed by this software. ? I paid €100 for this (more expensive for instance than Affinity Photo for instance, but I agree the volumes of sales are not the same...) and : You feel like the software is not finished (many bugs in the UI, some of them are described in the attached email thread) The documentation is incomplete (it was at least 3 weeks ago, I haven't checked since then), whole parts are missing. I feel like I am supposed to take a workshop to understand how to properly use this software and work around the bugs... No matter what the price of the software is, you do not release a fee-based software it if the documentation is incomplete... This is the basic rule #1 of software. Documentation IS part of the software. If you don't have time to document the software, then do not release it. Or hire someone to write the documentation. Or release it, but free & open sourced, with a disclaimer "Sorry I don't have time to maintain or document this software, but feel free to fork it". Of course bugs happen, and are acceptable if fixed someday. ? I'm really not in the habit of complaining about software, but I must admit I feel a bit obliged to do so. ? Meanwhile, I've switched back to Peter Mrhar's EDN for gold-toned VDB, which gives me satisfactory results. As a reminder, EDN is free, does not lock you with a specific operating system nor raster graphics editor? and is fully documented in a dedicated book (for sale) or in free videos on YouTube. (By the way, I just found a bad bug in EDN also (about the merge of two corrections), I just emailed Peter Mrhar about it.... :)) ? Your feedbacks are welcome !

Richard Boutwell Member Profile All Messages By This Member #19425 Here is a copy and paste from the v3 instructions from my support site: ? ? Step 1: Compare the areas where the transparency material covered is the same density as the coated edges to get your standard exposure time. Step 2: Find the white patch in that strip to find the blocking density for the time and process you are using. Step 3: Open the QuadToneProfiler-DN app and go to the Starter Curve Setup screen and change the boost slider so that the maximum black percentage label reaches that blocking density from step 2. ? ? The total ink load scales all the inks up and down by the percentage in the slider, and is what is used for using the open bite test utility for direct to plate photogravure. I generally recommend not adjusting this slider for the blocking density when using digital negatives, and only increase it it if the print from first linearization test is much too dark. ? The Black Ink Boost is what you will use to increase the blocking density for the Black and Yellow channels (which are now combined into a single control and not two separate controls like they were in the v1 and v2 of the QCDN apps) ? ? ?
