Description
Measure horizontal and vertical print-registration offsets from a target.
Print and screen geometry depends on coordinate scale, placed image size, bleed/inset definitions and pixel transparency. Placed pixels per inch differs from printer dots per inch, and a caller-chosen margin differs from a verified production tolerance. Empty-image conventions and threshold equality affect bounding results.
Measure horizontal and vertical print-registration offsets from a target.
When to use this tool
Use Print Registration Target Offset Vector when checking the stated artwork geometry, placement, screen angle or alpha-bound convention.
How to use the tool and how it works
- Enter targetX, targetY, printedX, printedY. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read offsetX, offsetY, magnitude. Use the output convention below.
Return printed-minus-target x/y offsets and their Euclidean magnitude using a common coordinate unit.1

| printedX | Printed X | Required. Finite number. |
| printedY | Printed Y | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| offsetX | printedX-targetX. | Required. Finite number. |
| offsetY | printedY-targetY. | Required. Finite number. |
| magnitude | Magnitude | Required. Finite number. |

}Limitations and assumptions
- The coordinate frame and measurements are supplied; no image registration, print alignment or tolerance is independently evaluated.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Inspect rendered artwork and verified production/device specifications for actual print quality, cropping, fit and manufacturing requirements.
