How to linearize settings to match paper

[hafsajoardar]

Hi, I am looking for a way to use L1300 and Epson original ink to print offset printing paper (TAKEO VENT NOUVEAU V and LBY Excellent Color, as well as some offset printing copperplate paper and uncoated paper).

I have tried Printfab these days. I tried to use the “Matte Inkget” setting, but the ink volume is still too wet even if it is limited to 100, which makes the color blocks blurry. I looked up some posts and modified the .tpr file, but even with a very low “DRange” setting, the deepest part of the two-color block (200%) and single-color block (100%) still has ink overflow. At the same time, the black mixed by CMY is too light, and the pigment black ink is difficult to adhere (after testing, the paper can only adhere to 30% of black ink without fading).

Is there any way I can print this kind of paper and get better results? At the same time, I hope to use black ink and manage the use of black ink (up to 30% of black ink can be used, which seems can be set in i1Profiler), rather than having Printfab add black ink.

This is my modified settings file and its printing effect (print settings: CMYKProof; No Correction; 5760dpi):

Hello,

please do not adjust the .tpr file. Instead, you can adjust the maximum ink amount in a printer driver specific file.
For the L1300, the file is

C:\Program Files (x86)\ZEDOnet\PrintFab 1.x\colors\DX4250.tpm

For the paper class "inkjet" and print resolution "5760dpi", please modify the following section

Code: Select all

[2880dpi_d120]
Channels=k,c,m,y
Gamma=550
Saturation=80 ;reduce as necessary e.g. to 40, 50 or 60
Bits=2
Levels=0,100
LValues_K = ...

Then you can create a new profile - add a new profile entry, print ink limit test line, print a profile color chart, measure with spectrophotometer etc. as outlined in this post:

Note: The drawback is that this will also affect PrintFab's built-in and other existing color profiles for this printer.

Thank you for your response! Based on your advice, I adjusted the Saturation parameter to 40, and achieved better printing results. However, I have a new question: even with the Saturation parameter set to 40, there is still some ink bleeding when the ink saturation limit is set to 300. Should I continue lowering the Saturation or restrict the ink saturation limit to 250?

Additionally, when using "Matte Inkjet Paper" setting (300g TAKEO VENT NOUVEAU V), I encounter issues where the front and end of the paper come into contact with the print head. Is there a parameter that can be adjusted to accommodate heavyweight paper without affecting print color(and use CMYK ink for printing)? In the case of the same type of paper with multiple thicknesses (ranging from 120g to 350g), can color calibration be applied only to the medium thickness (200g) and then extended to other thicknesses?

A sincere suggestion: the current method of modifying configuration files to adapt to various paper types is quite inconvenient. Every time I switch paper, I must adjust global parameters, which significantly increases the likelihood of errors and adds to costs, strongly hope that Saturation and settings related to paper thickness can be included in the printer profiles.

You are right, the method that we discussed is not convenient and it is not recommended by us.
The currently recommended solution is to select the minimun ink limit of 100. If the bleeding on the profile page is acceptable, the profile can be created (either through our profile measurement service of with a spectrophotometer).
If the ink amount should be too high in final prints, you can adjust the ink amount in the driver settings - tab "Main", slider "Intensity".

I recommend to use a saturation of 40 and to reduce the ink limit to 250 (or even further to 225 / 200 if necessary).

I will send you a modified driver file by email that lets you adjust the print head height.

It should be no problem to create a profile for the thinner paper and use it for the thicker paper.

I tried and found a new problem: when I lowered the ‘ink limit’ parameter to 225/200/175, I found that Printfab tried to replace CMY ink with black ink. Since black ink is pigment ink, I set ‘Saturation_K=13’ to ensure that black ink can adhere to the paper (at this time, black still looks rough), and if only CMY ink is used to print black, the color is too light. Even if the file is set to C100M100Y100, Printfab always prints black as K100; when MaxInk=180, the two-color block (like C100M100) will be added with black and become very rough.

I don’t know if there is a way for me to completely control the addition of black instead of being controlled by Printfab (limit MaxInk in Printfab and do not automatically add black)? I hope to use C65M65Y65K100 (Saturation=40, Saturation_K=13), or C65M65Y65K30 (Saturation=40, Saturation_K=40) to print the deepest black.

I thought of a possible abnormal method: cancel the ink limit in Printfab (Saturation=40, MaxInk=450), and then set ‘Total Ink Coverage’ to 225%, ‘Black Strart’ to 60%, and ‘Maximum Black’ to 30% in i1Profiler. This method seems feasible, but there is no way to limit the total amount of CMY channel ink to 195% separately (the color block will still spread when C100M100). My spectrophotometer has been borrowed by someone else, and I have not practiced this method for the time being.


If Printfab could limit the ink volume of each color channel (including the saturation of each color and the total ink limit of the CMY channel), and the addition of black ink could be controlled by the CMYK configuration file settings in i1Profiler, it would be perfect.

Non-original pigment black ink has caused many problems. I have decided to switch back to Epson original dye ink for black ink. This should allow the black ink to adhere to the paper, and perhaps it won’t be a problem for Printfab to manage the addition of black (all colors saturation=40 MaxInk=190).
