The measurable area of some integrated measuring devices can be smaller than the printable area of the printer. If a control strip is placed outside the measurable area, the measuring device will technically not be able to measure it, as shown in the following illustration of the measurable area of an Epson integrated measuring device.
Sketch illustrating the technical limitation.
The sketch illustrates that the problem is more likely to occur if multiple images are positioned in landscape orientation. Two pages are placed next to each other in the job. The gray area is out of range for the integrated measuring device. The second page in the job (and thus also the image control strip which is placed directly beneath the image) exceeds the measurable area and cannot be measured.
One strategy to solve this problem is to open the printed job from the History, rearrange the images and print the job again. The following table provides you with information which may help you in rearranging the images so that all control strips are placed within the measurable area.
Overview on the measureable areas
Epson printers:
| Printer | Paper Width (mm) | Measurable Area (mm) | Non-Measurable Area (mm) | Non-Measurable Area (inch) |
| Epson Stylus Pro 4900 | 432 | 395 | 37 | 1.46 |
| Epson Stylus Pro 7900 / WT7900 Epson SC-P 6000/7000 | 610 | 470 | 140 | 5.51 |
| Epson Stylus Pro 9900 Epson SC-P 8000/9000 | 1118 | 991.45 | 126.55 | 4.98 |
| Epson Stylus Pro 7890 | 610 | 470 | 140 | 5.51 |
| Epson Stylus Pro 9890 | 1118 | 991.45 | 126.55 | 4.98 |
Canon iPF printers:
The measurable area of the Canon iPF 6450 series is limited to the left, right and top side, so that control strips should always be placed at the bottom of an image.
Printer | Paper Width (mm) | Left Margin | Right Margin | Top Margin |
| Canon imagePROGRAF 6450 | < 550 | 30 | 30 | 110/170 |
| Canon imagePROGRAF 6450 | >= 500 | 30 | 87 | 110/170 |
Other strategies to ensure that a printed control strip can be measured:
Use job control strips instead of image control strips. Job control strips are always printed within the measurable area.
Please note that job control strips cannot be used for GMG OpenColor jobs.
- Workflow jobs: Use a nesting template and activate the option Place Control Strips within Measurable Area.
- If you are using an Epson Stylus Pro 7900 printer, use a 17'' roll. The measurable area completely covers the roll width.
