1. Measurement Notes

Measurement Principle

Refer to the measurement methods below to complete the measurement of a specific item.

Face the item from the printer's perspective, measure the item's left margin, top margin, width, height, etc., then pass the measurement results to the printer as required.

Plain Understanding

Imagine standing at the printer's position looking at the item, and measuring each distance starting from the print origin.

2. Parameter Details

The 4 Core Parameters

Parameter Description Unit Example Value
width Width of the print image mm 50.1
height Height of the print image mm 50.1
left Distance from the image's left border to the print origin's left margin (corresponds to the X start distance) mm 57.5
top Distance from the image's top border to the print origin's top margin (corresponds to the Y start distance) mm 12.3

Parameter Notes

  • Unit: All parameters use millimeters (mm).
  • Precision: One decimal place may be kept.
  • Viewpoint: Measure from the printer's perspective facing the item.

3. Circular Material Measurement

Measurement Example

Suppose a circular material is measured as follows:

Parameter Measured Value Description
width 50.1 mm Diameter
height 50.1 mm Diameter (width equals height for a circle)
left 57.5 mm Distance from left border to origin
top 12.3 mm Distance from top border to origin

left and top Calculation

For a circle, left and top are calculated as:

left = distance from image center to outer left border − circle radius
     = 82.5 − 50.1 / 2
     = 57.5 mm

top  = distance from image center to outer top border − circle radius
     = 37.3 − 50.1 / 2
     = 12.3 mm

Measurement Steps

  1. Measure the circle's diameter as width and height.
  2. Measure the distance from the image center to the left outer border.
  3. Calculate the circle radius = diameter ÷ 2.
  4. Calculate left = distance from image center to left − circle radius.
  5. Measure the distance from the image center to the top outer border.
  6. Calculate top = distance from image center to top − circle radius.

4. Square Material Measurement

Measurement Example

Suppose a square material is measured as follows:

Parameter Measured Value Description
width 55.1 mm Print-area width
height 55.1 mm Print-area height
left 5 mm Distance from left border to origin
top 10 mm Distance from top border to origin

Measurement Steps

  1. Measure the square's width as width.
  2. Measure the square's height as height.
  3. Directly measure the distance from the left border to the origin as left.
  4. Directly measure the distance from the top border to the origin as top.

5. Pixel-to-Millimeter Conversion

Why Convert?

The printer accepts dimensions in millimeters (mm), so if the image size is in pixels, it must be converted to millimeters.

Conversion Formula

Size (mm) = (Pixel size / DPI) × 25.4

Why Multiply by 25.4?

Because 1 inch = 25.4 millimeters.

Calculation Example

Suppose an image:

  • Size: 1200 px (width) × 1800 px (height)
  • Print resolution: 300 DPI

Calculation:

Width (mm)  = (1200 px / 300 DPI) × 25.4
            = 4 inches × 25.4
            = 101.6 mm

Height (mm) = (1800 px / 300 DPI) × 25.4
            = 6 inches × 25.4
            = 152.4 mm

Common DPI Reference

DPI Description
300 Standard-quality printing
600 High-precision printing
150 Fast printing

6. Frequently Asked Questions (FAQ)

Q1: Must the measurement unit be millimeters?

A: Yes. The printer accepts dimensions in millimeters (mm), so the measurement results must be converted to millimeters.

Q2: How many decimal places are needed?

A: One decimal place may be kept, e.g. 50.1 mm, 57.5 mm.

Q3: Where do left and top start from?

A: Measured from the print origin (origin):

  • left = horizontal distance (X direction) from the image's left border to the print origin.
  • top = vertical distance (Y direction) from the image's top border to the print origin.

Q4: How to fill width and height for a circle?

A: For a circle, both width and height equal the diameter.

Q5: How to determine the print origin?

A: The print origin is the origin of the printer's coordinate system, usually at a fixed position on the print platform. The exact position needs to refer to the printer manual or consult technical support.

Q6: What is the pixel-to-mm formula?

A:

Size (mm) = (Pixel size / DPI) × 25.4

where 25.4 is because 1 inch = 25.4 millimeters.

Q7: What is DPI?

A: DPI (Dots Per Inch) is print resolution, the number of dots per inch. Higher DPI means higher print precision.

Q8: What problems can measurement errors cause?

A: Measurement errors may cause:

  • Print position shift.
  • Print content exceeding the material bounds.
  • Print content too small or too large.

Measure carefully and verify multiple times when necessary.

Q9: Are measurement methods the same for different shapes?

A: The basic principle is the same, but the calculation differs slightly:

  • Square: directly measure width, height, left margin, top margin.
  • Circle: width and height are the diameter; left and top must be calculated.
