These study examples help you evaluate appearance alongside the requirements of your printed device. ## Appearance after exposure at 150 °C The six exposure times below span 1–30 minutes. ![Photographic detail of NanoPaper after the study condition of 150 °C for 1 minute](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-150c-1min-20261026.png?v=1793028806) **150 °C**1 min ![Photographic detail of NanoPaper after the study condition of 150 °C for 3 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-150c-3min-20261026.png?v=1793028811) **150 °C**3 min ![Photographic detail of NanoPaper after the study condition of 150 °C for 5 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-150c-5min-20261026.png?v=1793028816) **150 °C**5 min ![Photographic detail of NanoPaper after the study condition of 150 °C for 10 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-150c-10min-20261026.png?v=1793028821) **150 °C**10 min ![Photographic detail of NanoPaper after the study condition of 150 °C for 20 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-150c-20min-20261026.png?v=1793028825) **150 °C**20 min ![Photographic detail of NanoPaper after the study condition of 150 °C for 30 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-150c-30min-20261026.png?v=1793028829) **150 °C**30 min Photographic details from an unprinted NanoPaper development study at four nominal temperatures and six durations. Lighting, shadows and your display affect appearance. Use the current TDS for processing guidance. ## From an exposure to a process A printed device may experience several heating steps. Consider the complete sequence: the same peak setting does not always mean the same exposure. ### Temperature + time Record the setting and the exposure duration together. A brief heating step and an extended hold can produce different results. ### Equipment + support Record how heat reaches the sheet, including the oven, platen or roller, and how the sheet is supported. ### The complete sequence Keep drying, curing, lamination and assembly steps in one process record. Inspect the construction after the full sequence. ## Compare another temperature. Each temperature uses the same six exposure times. 180 °C ![Photographic detail of NanoPaper after the study condition of 180 °C for 1 minute](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-180c-1min-20261026.png?v=1793028846) **180 °C**1 min ![Photographic detail of NanoPaper after the study condition of 180 °C for 3 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-180c-3min-20261026.png?v=1793028850) **180 °C**3 min ![Photographic detail of NanoPaper after the study condition of 180 °C for 5 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-180c-5min-20261026.png?v=1793028854) **180 °C**5 min ![Photographic detail of NanoPaper after the study condition of 180 °C for 10 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-180c-10min-20261026.png?v=1793028859) **180 °C**10 min ![Photographic detail of NanoPaper after the study condition of 180 °C for 20 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-180c-20min-20261026.png?v=1793028864) **180 °C**20 min ![Photographic detail of NanoPaper after the study condition of 180 °C for 30 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-180c-30min-20261026.png?v=1793028868) **180 °C**30 min 200 °C ![Photographic detail of NanoPaper after the study condition of 200 °C for 1 minute](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-200c-1min-20261026.png?v=1793028887) **200 °C**1 min ![Photographic detail of NanoPaper after the study condition of 200 °C for 3 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-200c-3min-20261026.png?v=1793028891) **200 °C**3 min ![Photographic detail of NanoPaper after the study condition of 200 °C for 5 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-200c-5min-20261026.png?v=1793028897) **200 °C**5 min ![Photographic detail of NanoPaper after the study condition of 200 °C for 10 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-200c-10min-20261026.png?v=1793028901) **200 °C**10 min ![Photographic detail of NanoPaper after the study condition of 200 °C for 20 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-200c-20min-20261026.png?v=1793028904) **200 °C**20 min ![Photographic detail of NanoPaper after the study condition of 200 °C for 30 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-200c-30min-20261026.png?v=1793028909) **200 °C**30 min 220 °C ![Photographic detail of NanoPaper after the study condition of 220 °C for 1 minute](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-220c-1min-20261026.png?v=1793028920) **220 °C**1 min ![Photographic detail of NanoPaper after the study condition of 220 °C for 3 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-220c-3min-20261026.png?v=1793028924) **220 °C**3 min ![Photographic detail of NanoPaper after the study condition of 220 °C for 5 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-220c-5min-20261026.png?v=1793028929) **220 °C**5 min ![Photographic detail of NanoPaper after the study condition of 220 °C for 10 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-220c-10min-20261026.png?v=1793028933) **220 °C**10 min ![Photographic detail of NanoPaper after the study condition of 220 °C for 20 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-220c-20min-20261026.png?v=1793028937) **220 °C**20 min ![Photographic detail of NanoPaper after the study condition of 220 °C for 30 minutes](https://cdn.shopify.com/s/files/1/0729/9986/2324/files/nanopaper-v11-thermal-220c-30min-20261026.png?v=1793028942) **220 °C**30 min ## Evaluated processing examples ### Silver-ink processing 150 °C · 30 minutes [Open the current TDS →](https://docs.nanopaper.io/material/tds/?hsLang=en) ### Copper-ink roller processing 200 °C · six passes Approximately 30 seconds of estimated cumulative residence in the laminator’s heating zone, using the original motor.

A machine setting and a measured sheet temperature describe different quantities; record each when available. ## Evaluate appearance, geometry and function ### Appearance Keep an unprocessed reference coupon and compare color under consistent lighting. If the substrate remains visible, define the finish your application needs. ### Geometry and handling Check flatness, registration and handling after processing and conditioning. ### Printed performance Measure continuity, resistance, adhesion or device response using the acceptance criteria for your application.
