You have designed a perfect wedding invitation, press the print button, and suddenly, your printer jams, and the roller marks are spread all over your thick card. Or maybe worse: the ink smudges because your printer was not set for the heavy paper. The situation will probably frustrate you, and you are wondering about the solution. 

Good News? This guide will cover the solution to this problem. It is essential to understand and learn how to print on cardstock, which becomes a game-changer for you. We will also tell you about how to choose the weight, adjust settings to rear feed printed for cardstock, platen gap/thick paper setting, and solutions to alignment problems and smudges.   

How to Choose the Right Cardstock Weight?

When learning how to print on cardstock, the first step involves choosing the accurate cardstock weight. In the US, the Ib (pound) is the basis weight, which means the weight of 500 sheets of a size. The GSM is a metric that is grams per square meter, which compares the papers in the most perfect way. Use the cardstock weight to GSM conversion chart (approximate; finish/caliper can vary). 

• 65 lb = 176 GSM – Great for flyers and light greeting cards. 
• 80 lb = 216 GSM – invitations/postcards (most home printers handle this)
• 110 lb = 300 GSM – premium, often needs straighter feed paths

Most home printers are secure for less than 80 lb / 216 GSM. If you use heavy stock, then plan a single-sheet manual feed or rear feed printer. Choose the weight based on the use cases: greeting cards and invitations (80 lb), packaging backers or premium invites (110 lb). For sharp folds, go with the paper grain direction for printing & folding, and fold with the grain to avoid cracking. 

What is Paper Grain Direction for Printing & Folding?

Direction of paper grain used to print and fold: the direction in which the majority of fibers run in a sheet. When the fibers are placed running along the long side, it is long-grain; when along the short side, it is short-grain. 

Fold with the grain, and the fibers are flowing- your fold is sharp, and it does not snap. Fold against the grain and you will find a cracking sound or a rough edge. Grain effects also feed: when a grain is not planking the roller path of the printer, jams, skew, or roller marks can be obtained.

Quick test: Hold the sheet and bend it on both ends, and the direction that you find it easy to bend is the grain.

Pro tip: For various desktop printers, it is better to use short-grain card stock, particularly with heavy stocks. When there is still resistance, try a rear feed printer with cardstock or a manual single-sheet feed to make the path less curvy.

Set Up Your Printer Correctly to Print Cardstock

When you are going for printing on a heavy cardstock, the safest way to print is a rear-feed printer. The back feed provides the paper with a more straight path, which minimizes bending, jamming, and roller marks. 

For thicker media, you can either use the platen gap / thick paper setting of your printer driver. This commands the printer to raise the print head slightly in order to avoid smearing of ink on the surface. 

This option will normally be under Paper Settings or Media Type in Epson, Canon, and HP printers. Choose Cardstock, Heavy Paper, or Thick Paper. And, when working with material more than 100 lb (270 GSM), manual single-sheet feed is better than loading a stack. This maintains low pressure, prevents feeding errors, and provides cleaner, sharper prints.

Use Custom Paper Size & Tray Selection for Thick Stock

The majority of printers consider the Letter (8.5"×11") unless you tell them about your preferred size. It is recommended to set custom paper size & tray selection for thick stock if you want accurate borders and fewer jams on the cardstock before printing.  

Windows: File - Print - Printer Preferences/Properties - Paper/Quality (or Layout) - Paper Size – Custom - enter width/height and save.

macOS: File – Print – Paper Size – Manage Custom Sizes  +  enter width/height – set minimal margins and click on OK.

After this process, choose Media Type = Cardstock/ Heavy paper and pick the accurate tray. We recommend that you use the bypass/manual or rear feed for thick sheets (straighter path); the standard tray is fine for lighter stocks (e.g., 65–80 lb). Load single sheets at a time when dealing with heavy cards. Place the side guides on the side without tightness to ensure no skew. A cardstock rear feed printer with your printer will significantly decrease misfeeds and curl.

What are the Advanced Printing Options?

If you want to know how to print double-sided on cardstock without misalignment, then run a test sheet and pick the short or long edges to flip, which matches your layout, and maintain scaling at 100%. If you want you can get custom cardboard boxes from us as well.

For borderless printing on cardstock, we recommend adding ?” bleed, exporting crop marks, and printing slightly oversize and trimming.  

With holographic/pearlescent cardstock, you can choose laser/offset; many inkjets smear unless pigment + rear feed. The Colors include: 300 DPI, consistent bleed margins, and basic ICC soft-proofing (CMYK if necessary). For best printing results always collaborate with the best custom printed boxes maker like us.

FAQS

How can I prevent ink smudging on cardstock?
Use pigment ink instead of dye ink because it dries faster and resists smearing. Also, allow sheets to fully dry before stacking.

Conclusion

To sum up the overall article, we conclude that printing on cardstock is not very frustrating. If you choose the right weight, check paper grain direction, and use the above mentioned settings, you can definitely eliminate all the jams and smudges. 

The advanced printing options that we mentioned, such as duplex accuracy, borderless printing, or handling pearlescent cardstock, will make your project more professional. It is recommended to use a troubleshooting matrix if you want quick fixes and you can easily achieve clean and sharp results on invitations, crafts, or business cards.
