Match the paper to your printer by exact model, ink or toner process, supported weight and feed path. GSM alone does not establish compatibility, and Valenna cannot guarantee a particular printer model.
🖨️ How to check, step by step
- Find the maximum paper weight for your exact model in the manual or the manufacturer's media specification, not a similar model in the series.
- Check the limit for the tray you will use. The cassette, multipurpose tray and rear feed can differ, and the supported sizes and media types too.
- Look for a rear manual feed or bypass tray, which gives a flatter paper path for thick stock.
- Select the heavy-paper media setting so feed speed, ink use or fuser behaviour suit the stock.
- Print one test sheet and check feeding, colour, drying, toner adhesion, curl and duplex alignment before loading the pack.
⚠️ Warning: do not force stock through an unsupported tray. Even inkjet- or laser-rated cardstock can fail to feed if the weight limit or paper path is unsuitable.
📏 Thick cardstock, 250 to 350gsm
- Confirm the model supports that weight in the intended tray.
- Use a rear feed or bypass tray, and load only the recommended number of sheets.
- Keep edges undamaged. Many 350gsm sheets are meant for firm cards and covers cut and finished by machine. Ask us if a thinner sheet could work.
📋 Other things to check
| Requirement | Why it matters |
|---|
| Inkjet or laser | Coatings and adhesives may suit only one process |
| Finish | Matte, glossy and uncoated reproduce print differently |
| Printing sides | A single-sided coating is not double-sided printable stock |
| Use | Do not use paper for food contact or other specialised purposes unless confirmed for the product |
💬 When asking Valenna
Send your printer model, ink or toner type, size, GSM range, finish, printing sides and quantity. If compatibility cannot be confirmed from those details, test a small pack before buying production quantities.

Is a heavier sheet always better?
No. The right weight depends on the printer and the project.
