CRITICAL: Print at exactly 100% scale. Do NOT select "Fit to Page" or "Shrink to Fit."
In your print dialog: Scale = 100% | Paper = Letter (8.5" × 11") | Margins = Default
For best results: Print on matte photo paper or heavy cardstock (not glossy — gloss causes reflections).
After printing, verify: Measure the 10mm scale bar with a ruler. It must be exactly 10mm. If not, adjust print scale.
Laminate the card for durability (matte lamination only, NOT glossy).
Use this calibration card whenever the same tooth shade, model, or restoration needs to be reviewed by clinic and lab from photos or video. Place the card on the same plane as the model or intraoral reference so TrazaLab can compare color, distance, and scale with less guesswork.
For consistent captures, keep lighting stable, avoid shadows across the checkerboard, and leave the full card visible in the frame. Do not crop the card out before uploading. If the checkerboard is warped, wet, glossy, or partly hidden, print a fresh card and repeat the capture.
Typical use cases include shade review, before-and-after documentation, wax-up approval, implant component verification, crown try-in photos, and model photos where the lab needs a reliable size reference. The checkerboard gives the software high-contrast corners, while the gray patches help compare exposure and white balance across different phones and clinic lights.
The card is not a diagnostic device and does not replace clinical judgment, calibrated photography equipment, or laboratory protocols. It is a practical reference for communication: the clinic and lab can look at the same capture, confirm that scale was not distorted, and discuss color or anatomy with a shared visual anchor.
Store one printed card in each operatory or intake station. When a case includes multiple views, keep the card visible in at least one frontal view, one lateral or model view, and one close-up. Consistent capture habits make files easier to review later inside TrazaLab.
If a case is especially sensitive, such as an anterior crown, full-arch restoration, implant guide, or remake review, capture one extra photo with the card beside the relevant teeth or model. That extra reference can save a follow-up message because the lab can verify orientation, approximate size, and lighting conditions from the first upload.
Replace the card when corners bend, ink fades, the paper gets stained, or lamination creates reflections. A clean card takes seconds to print and helps keep clinical photos useful across the full case record.
