RTI Calibration Services

RTI includes calibration with every new software purchase. Within the technical support period RTI will calibrate all of your output devices including platesetters, imagesetters, printing presses and digital proofing devices. You can mail the targets to us and we will take readings at our office using our color spectrophotometer or plate densitometer. Once the calibration is complete we can email the calibration file or remotely connect to your computer and install the calibration data. If you are using another type of Harlequin RIP, another workflow or you are past your technical support contract, RTI can assist with the calibration of your output devices for $295.


Harlequin RIP Calibration Procedures

Calibrating an Imagesetter or Platesetter. Verify that the page setup you are going to calibrate has the correct exposure setting. Please refer to your equipment manual to find the valid exposure range and output an exposure sweep if necessary from the RIP in order to figure out the best exposure setting for your device. To output an exposure sweep you will need to go to the Output - Print Calibration menu then select your page setup on the right hand side. Next, you will enter a From value and a To value at the bottom of the window along with a Step value (note: you must know the valid range of your machine). Example: From: 100 To: 200 Step: 10 would give you exposure targets at 100, 110, 120, 130, 140, 150, 160, 170, 180, 190 and 200. Once you have entered your From, To and Step values you will need to click Print Exposure Sweep.

If you are certain you have the proper exposure set the next step would be to place the exposure setting into your page setup within the RIP. Go to the RTI RIP-Kit menu and scroll down to page setup manager. On the right you will see an exposure setting. Enter the appropriate value here. Next, print an uncalibrated target (monochrome only) from the Output - Print Calibration menu. Mail this target to RTI. We will email you back the calibration numbers which can be entered back into the Calibration Manager of the RIP or we can remotely connect to your RIP computer and enter the values for you. You will need to apply this calibration in the page setup under the calibration section and then print a calibrated target (monochrome only) from the Output - Print Calibration menu. Check to see if the output is accurate; you may also want to mail this target to RTI so that we can verify the calibration is correct. A sample uncalibrated target is shown below.

Calibrating a Printing Press. Before outputting a press calibration the Imagesetter / Platesetter must be calibrated. Verify that the page setup you are going to calibrate has the correct exposure setting and that it is also using the correct Imagesetter / Platesetter Calibration. Next, print an uncalibrated press target from the Output - Print Calibration menu. Mail this target to RTI. We will then email you back the calibration numbers which can be entered back into the Calibration Manager of the RIP. Next, you will need to apply this calibration and print a calibrated press target from the Output - Print Calibration menu. Check to see if the output is accurate; you may also want to mail this target to RTI so that we can verify the calibration is correct.

Calibrating an Inkjet Printer or Digital Proofer. Verify that the page setup you are going to calibrate has ProofReady set to the correct paper type and that NONE is selected for all of the calibration settings before printing any calibration targets. Next, print an uncalibrated target to the inkjet page setup from the Output - Print Calibration menu. Mail this target to RTI. We will then email you back a calibration file that can be imported into the RIP. We can also remotely connect to your RIP computer and import the file for you. You will need to apply this calibration in the page setup under the calibration section and then print a calibrated target from the Output - Print Calibration menu. Check to see if the output is accurate; you may also want to mail this target to RTI so that we can verify the calibration is correct.



Frequently Asked Questions

What is the difference between 'Edit from Uncalibrated' and 'Edit from Calibrated' buttons within the Calibration Manager? The 'Edit from Uncalibrated' button is used to view your current calibration values. The 'Edit from Calibrated' button is used when you take screen readings from a calibrated target. This would be used if you printed a calibrated target and the screen values were still slightly off. By editing the calibrated target you can enter another layer of calibration on top of your existing calibration.

What are the rules when entering data into the calibration manager?
No two numbers can be the same (Correct: 0,2,4,7,9 / Incorrect: 0,2,2,7,9).
The numbers must all either be increasing or decreasing in value (Correct: 0,2,4,7,9 / Incorrect: 0,2,4,3,9).
The numbers must be between 0 and 100. 0 is also always 0 and 100 is always 100 since you cannot print a negative dot and you cannot print over 100.


PDF Instructions

PDF Instructions for Calibrating the Harlequin RIP and Prepress Workflow. If you are going to calibrate your imagesetter or platesetter, you will need to know the exposure range of your particular imagesetter or platesetter. To find out this information please refer to your imagesetter or platesetter user manual.
