Tablet Pressure Curve Tool


This application is designed to improve experience with Wacom tablets. Sometimes you have to press your pen with unnecessary force to get maximum opacity. It is possible to modify pen response through tablet configuration, but the available options are limited and maximum required force is unchanged. This application allows you to modify all three control points of tablet sensitivity curve and subsequently achieve custom and improved pen sensitivity.


Tablet Pressure Curve Tool  version 2.1 (30/9/2015)
(for Windows 7/8 with Wacom tablets)

Some application actions require elevated privileges to run correctly.

  1. Any way to get this to work with windows 10? ‘The destination file cannot be created’

  2. I have a problem om the Yosemite version. I get the following message “unable to write new preference file” when I try to save my changes.
    Can anyone help me out with that?

  3. Is there a version available for Huion tablets ?

  4. Hello, fantastic tool.

    I have a question regarding tablet device detection. I am using two tablets at the same time on my machine (a Cintiq21UX and a “2015 Intuos” non pro – that is to say, a Bamboo really) and I am having trouble pointing the Curve Tool to one or the other. I assume that the two devices rely on different .dat files, but I am not sure.

    Last time I ran the tool, it successfully allowed me to tweak the response curve of the Intuos/Bamboo, which makes sense as it was the only tablet device plugged at that time ; but now that I got my Cintiq back, the Pressure Tool defaults to it and does not let me edit the pressure settings of the Intuos/Bamboo anymore.

    Things of note : surprisingly enough the two tablets are compatible driver-wise. I am using 63.11-4.

    I still have to see what happens when unplugging either of the devices, but of course it would be easier if there was no need for it.


    • Thanks for your feedback. I Am sorry, that the tool is not able to be helpful in your situation. I don’t have all the Wacom data file / configuration structure available.
      If the driver uses, in your case, two separate files (the application allows to choose in some cases the correct file) it should be possible to manually open the desired one. (File/Open…)
      If the driver is separating the two devices within the file then the tool is unable to deal with this situation and probably selects the first device :-(
      There also should be some settings for the pressure within the Wacom driver itself, because Wacom, after users started to manually adjusting the pressure, implemented and enabled it for some devices.
      In both cases it would be really helpful to send me your current configuration file/files (or configuration backup from Wacom desktop center) and i will try to analyze and identify the problem and hopefully improve the tool.

      • Hello Karel, thank you for the follow-up.
        I will try to dig deeper into this over the coming days (for instance by rebooting my machine with either tablet plugged, to see which one show up). And will get back to you as soon as I learn more.

        Regarding Wacom’s implementation of pressure curve editing : indeed, it is available on “high end” models (intuos “pro”, cintiqs) but they unfortunately left it out for the cheaper models (intuos “non pro” = bamboo).

        I’ll get in touch with you again soon. Thank you for the follow-up again :)

      • Hi again Karel – sorry for my late reply, projects got in the way !

        Here is a Wacom_Tablet.dat file generated by my setup :

        Looking at it in notepad does reveal that the two tablets are listed in it, respectively as “Cintiq 21 UX 2” and “Intuos PS” (this is an Bamboo-Intuos, not a Pro).

        I hope this helps !

        • Thank you very much for your reply. The configuration file you have provided is really helpful. The file contains example how is Wacom organizing configuration of multiple tablets, so I will be able to update my tool to support this situation and allow users to choose correct tablet when they are using more of them.

  5. Hey mate! This looks like a very interesting tool. I am wondering, is this compatible with a Wacom Bamboo Create (CTH670). I would love to give it a try but I just wanna make sure before I iistall it. Thanks in advance for your comments!

    • The tool should be compatible even with Wacom Bamboo tablets, but honestly i was unable to test it with exactly this device. However – there are two main driver packages supplied by Wacom (for cheaper and for professional tablets) and these driver packages are both supported. There is no installation necessary – just unzip and run. The tool does modifications only to Wacom configuration file (and creates backups in application folder). If you don’t like it, just delete the folder where this tool is unzipped. After you run the tool it will show you whether your tablet is detected or not.

      • Hey there mate! I downloaded and unzipped the tool, and it detects my tablet 😀 I will sure give it a proper test tomorrow when I return home and give you feedback. Thanks mate!

  6. Hello there, thank you for the pressure tool.

    I think i ahve a problem with it, i dont think it works. I run windows 7 x64, i run the programm with administrator right. When i click apply changes, there is some windows command line window appear, it looks like it trying to do something, but i see “Wrong service name” appear 2 times in that window. After that it asks me to press any key to proceed and it closes.

    When i test chnages in Photoshop, i dont sure i see any. Any advice? :) I tryed to put maximum pressure sensivity very low (almost the botoom of the axis) but i still dont see any noticable chnage.

    Thank you :)

  7. Can you please make program support not wacom tablets, such as Trusts, Geniuses, etc. Most of them uses same macrokey manager, so it would be easy to add them in.

    • I’m sorry, but this tool is designed or wacom, because it is possible to modify wacom configuration files. This is driver-specific tool and it is not possible to easily extend functionality of this tool to another manufacturers :-(.

      • Hey ive used your Tool fort a Long time on my Desktop w/ Cintiq ans it Works linke a Charm.

        Now i Won a surface pro 2 could you Try to male it work on that device top? Tat would be amazing!

        Thanks for the good work!

  8. A couple bug reports:

    The settings on for my Bamboo Capture (CTH-470) on Win7 64bits, with driver version 5.3.3-3, keep getting reset (without me even opening the Wacom Control Panel applet). The automatic service reset isn’t working (I tried manually resetting the service but it doesn’t seem to get reloaded properly); to test it I log off and back in, sometimes it work sometimes it doesn’t, I’m not sure what’s the variable.

    And the lower threshold is overwritten to be 9 less (or perhaps 8, I forgot) than the upper threshold if it is not; and if you set the upper threshold to a too low value the lower threshold overflows (this might be a bug on Wacom’s side, but still shows the numbers are being overwritten).

    ps: Btw, could you please implement a simple painting thing inside the app to test new profiles before applying them, letting us draw with options of having brush size, opacity and/or hue dependent on the pressure according to the profile currently displayed on the the program?

    • Sorry for my really slow reply and thanks for the report. I will investigate these problems, but right now Im really busy at my work so it is not possible for me to actively maintain this tool. I hope, that the situation will change and this tool will get some much-needed attention.

  9. Thanks for that info Karel! I’ll try to keep it as much as default as possible when tweaking stuff.

    And about tweaking, I have an annoying issue right now. I’m trying to lower the needed force for maximum pressure on my 1024 levels Surface pro 2. I started by doing the same as I did with the intuos, keeping a straight line and just lowering the max input. Something like 780 instead of 1024.

    However I soon realized that the new range of pressure is way too low. I can’t really control it as I would with the intuos (obviously due to the 2048 levels). It’s just too compressed.

    So what Im thinking now is making a curve as opposed to a straight line, so that the “path of pressure” has the same length as it would had I not lower the max pressure.

    In your opinion, what would be the best way to make that curve without ruining the opacity range?

    • The “best way” is kind of slippery slope, because each person prefers different response of the pen. I would recommend to investigate settings in your applications, because their internal settings can also make a huge difference in pressure settings (also pressure settings (min. /max. opacity thresholds) each brush). Limiting the sensor is a “hard way” – it works but the price is (with huge tweaks) loss of pressure levels. The tool should allow you to experiment with different curves and settings and also – there should be folder with backups of configuration files after each modification so – feel free to find what suits for you.
      For me also was a good way to improve myself to learn to draw “lighter”. I have a “heavy hand” so i was drawing this way on tablet, but it takes some conscious effort to learn to draw little bit differently.

  10. works great on my surface pro2 also works with the connected lenova thinkvision touch screen monitor.
    this is running windows 8 64 bit on the surface pro 2.
    to get it to work I unticked auto detect services and selected wtabletisd from the drop down.
    this allowed me to adjust the pressure curve on both digitizer screens.
    great tool.

    • I’m happy that the tools works for you even on Windows 8. Good luck with all the creative work :-)

    • Hi,

      I read you managed to make it work on your SP2 but I can’t. When I open the tool it says “no service available” and I can’t untick autodetect, it’s greyed out. I have the wacom drivers installed instead of the default windows one, maybe that’s the problem.

  11. Heyyy Karel!

    I just got a new intuos pro, running latest drivers.

    I was tweaking the sensitivity and noticed that lower threshold starts at 81, same as lower point, and upper threshold is actually 97.

    That is the opposite of what you described in a document I found online, in which you say upper threshold equals lower point.

    Any idea why wacom changed that behavior? What could be the practical effects of that? I cant seem to feel differences when I invert the values.

    • I believe that these threshold values are implemented as safe margins for the pen. These values would prevent misreads and erroneous behaviors of the pen even after heavy usage. So, the values are based on actual hardware (that differs from model to model) and its sensitivity and it is set by wacom engineers with taking into concern all these elements even if it could mean, that they sacrifice some sensitivity for better long-term reliability.
      The sensors are more sensitive, but the pen could wear out and produce after a certain time some erroneous behavior on the “end” of the measurement scale. The tools allows to change these limits so it is possible to improve the sensitivity behind “factory defaults” which usually works without problems.
      The values that you encountered are specific for the device – values you found in the text was specific for some obsolete graphire tablet with 512 values of pressure sensitivity – what was high value for scale 0-512 (or difference between points) is actually quite low value on the scale 0-2048 and it is probably unnoticeable for the user.

  12. not work with win8.1 64bit and intuos 4 :(

    i open (in admin mode) set, and the first time nothing happen
    i open again (in admin mode) set, and seems to work because i close re-open and i can look the my setting.

    Open Photoshop cs6 or cc, and my curve not work, i open again the software, and my setting are again the default….

    in win 7 it work…. but in 8 not.. :(

    have some tips for me ?

    • I’m sorry, but Windows 8 are not supported by this tool (yet).

      The tool is based on older framework that does not support 64-bit systems. To make it work properly it would be necessary for me to buy a new version of development environment (quite expensive) or rewrite the whole thing in other more free / multi-platform way. This solution requires a lot of time that i don’t have now.

      At least is still should be possible to manually open Wacom configuration file. Edit values. Save the file and reboot operating system. That should apply the modified settings. The tool is blank probably because it is unable to find config. file location automatically — the location changed in Win8.

  13. is there a way to use the tablet in vertical placement ,rather than 0/180 it would be 90/-90 ???

  14. Hello!

    Does anyone know what the parameter PRESSURE SAFTEY MARGIN stands for?

    I’m trying to figure out why my surface pro sets that value to 0 and my cintiq sets it to 2.

    What are its practical implications?
