What bleed means and why your print might get cut wrong without it

Choosing the right paper specification can turn a good academic report or client presentation into an impressive, tactile artifact. Most people who have a print job rejected or returned look back at their paper choice as the culprit.

Understanding GSM (Grams per Square Metre)

GSM is the weight of a single sheet of paper measured in grams per square metre. Higher GSM means thicker, heavier, and generally more premium-feeling paper.

• 65\u201375 GSM (Standard Copy Paper): Lightweight, cost-effective, and best suited for rough drafts, lecture notes, and single-sided study sheets. Thinner paper shows bleed-through on double-sided prints.
• 80\u2013100 GSM (Executive Bond / Premium Copy): Heavier opacity with crisp ink absorption. Ideal for project submissions, formal resumes, and double-sided printing without bleed-through. This is the most common choice for professional documents.
• 120\u2013160 GSM (Art Paper): Used for high-quality flyers, brochures, and portfolios. Substantially thicker with a smooth finish.
• 200+ GSM (Cardstock / Glossy Photo): Perfect for cover pages, photo prints, certificates, business cards, and anything that needs to feel solid in hand.

Simplex vs Duplex Printing

Printing double-sided (duplex) cuts paper consumption by 50% and produces bookstore-quality bound reports. When selecting duplex on HDPrint, the preview accounts for margin gutter offsets so that spiral and comb binding work cleanly.

For duplex work, avoid anything below 80 GSM — the bleed-through will make the document unreadable on one side.

Matching Paper to the Print Job

| Use case | Recommended GSM | | ---------------------- | ----------------------- | | Drafts / scratch notes | 65\u201375 GSM | | Academic reports | 80\u2013100 GSM | | Resumes and letters | 90\u2013120 GSM | | Flyers and posters | 120\u2013170 GSM | | Business cards | 300\u2013350 GSM | | Photo prints | Glossy 180\u2013200 GSM |

Practical Takeaway Checklist

Before ordering your next print job, ask yourself:

• [ ] Is this single-sided or double-sided? (affects minimum GSM)
• [ ] Does the paper colour matter? (bright white vs natural / cream)
• [ ] Do I need a specific finish? (matte, gloss, silk, uncoated)
• [ ] Is there a bleed area if this is a full-coverage design?
• [ ] Does the receiving institution have a paper specification?

FAQ

Is 75 GSM okay for a thesis submission?

Most institutions specify a minimum of 80 GSM for thesis submissions. Check your institution's style guide before ordering. If in doubt, 100 GSM bond is the safest default.

What is the difference between gloss and matte paper?

Gloss paper has a shiny coating that makes colours look more vivid and provides some protection against smudging. Matte paper has no coating, absorbs ink more, and gives a softer, professional look. For text-heavy documents, matte is usually preferred. For photo prints and marketing materials, gloss is usually better.

Can I use cardstock in a regular desktop printer?

Most laser and inkjet printers can handle up to 120 GSM without issue. Above that, you need a machine rated for thick stock. Check your printer manual before sending 200+ GSM through a standard office printer — it can cause jams.
