75 gsm<\/strong>: lighter, often chosen for high-volume internal documents and draft printing.<\/p>\n<\/li>\n
- \n
80 gsm<\/strong>: a touch heavier, often preferred for duplex reports and external-facing documents where opacity and feel matter.<\/p>\n<\/li>\n<\/ul>\n
\n
Bottom line: gsm changes feel<\/em>, stiffness<\/em>, and often opacity<\/em>. It does not guarantee particular jam rates or universal compatibility.<\/p>\n<\/blockquote>\n

<\/a><\/p>\n75 gsm vs 80 gsm: thickness, stiffness, feel<\/h3>\n
- \n
- \n
75 gsm<\/strong> feels lighter in hand and can reduce paper costs per ream.<\/p>\n<\/li>\n
- \n
80 gsm<\/strong> feels more substantial and may handle duplex jobs with less show-through, depending on brand and device setup.<\/p>\n<\/li>\n<\/ul>\n
How gsm influences duplex, curl, and show-through<\/h3>\n
- \n
- \n
Duplex:<\/strong> Heavier stocks often look cleaner in duplex mode. Test your own devices to confirm.<\/p>\n<\/li>\n
- \n
Curl:<\/strong> Storage conditions and printer heat settings matter. Slightly heavier sheets may resist curl better, but driver profiles and humidity control are key.<\/p>\n<\/li>\n
- \n
Show-through:<\/strong> Heavier, more opaque sheets can reduce visible text\/images from the reverse side.<\/p>\n<\/li>\n<\/ul>\n
\nPrint Quality & Performance in Real Devices<\/h2>\n
Laser vs inkjet expectations<\/h3>\n
- \n
- \n
Laser printers<\/strong> fuse toner with heat. Slightly stiffer, smoother sheets (often 80 gsm lines) can deliver crisper text and solid fills for reports.<\/p>\n<\/li>\n
- \n
Inkjet printers<\/strong> lay liquid ink. Surface treatment varies by brand; test both weights for text density, line sharpness, and drying.<\/p>\n<\/li>\n<\/ul>\n
Opacity, brightness, whiteness\u2014when higher numbers matter<\/h3>\n
- \n
- \n
Opacity:<\/strong> Helps control show-through during duplex work.<\/p>\n<\/li>\n
- \n
Brightness\/whiteness:<\/strong> Can improve perceived contrast for text and charts. Extremely high whiteness is not always \u201cbetter\u201d\u2014aim for legibility, brand consistency, and how your graphics render.<\/p>\n<\/li>\n<\/ul>\n

\nCost & TCO: When 75 gsm Saves vs When 80 gsm Pays Off<\/h2>\n
Cost-per-ream vs cost-per-usable-page<\/h3>\n
- \n
- \n
75 gsm<\/strong> can lower cost per ream for draft-heavy workflows and internal documentation.<\/p>\n<\/li>\n
- \n
80 gsm<\/strong> can pay off when duplex readability matters (fewer reprints, clearer external documents).<\/p>\n<\/li>\n
- \n
Compare usable<\/em> output quality, not just the sticker price per ream.<\/p>\n<\/li>\n<\/ul>\n
Worked example:<\/strong>
If 75 gsm saves a few percent per ream but triggers extra reprints on duplex reports, your cost per usable page<\/strong> may rise. Run the 10-minute test below to learn which weight minimizes reprints for your exact content mix.<\/p>\nShipping, storage, and handling<\/h3>\n
- \n
- \n
Heavier stocks increase shipment weight and warehouse load.<\/p>\n<\/li>\n
- \n
Confirm carton dimensions<\/strong>, cartons per pallet<\/strong>, and pallet weights<\/strong> before ordering.<\/p>\n<\/li>\n
- \n
Store cartons in a dry area; acclimatize<\/strong> reams to office conditions before opening to help limit curl and misfeeds.<\/p>\n<\/li>\n
- \n
Align on Incoterms<\/strong> (e.g., EXW, FOB, CIF, DDP) and your target delivery window before comparing quotes.<\/p>\n<\/li>\n<\/ul>\n

\nSustainability Options<\/h2>\n
- \n
- \n
Recognized chain-of-custody schemes include FSC<\/strong> and PEFC<\/strong>.<\/p>\n<\/li>\n
- \n
Verify<\/strong> claims in the public database using the supplier\u2019s certificate details. Avoid relying solely on packaging logos.<\/p>\n<\/li>\n
- \n
Recycled lines:<\/strong> Modern recycled papers often perform well for standard office use. Always test the specific SKU on your devices.<\/p>\n<\/li>\n
- \n
Packaging & recyclability:<\/strong> Check whether outer cartons are recyclable and follow local guidance for wrap disposal.<\/p>\n<\/li>\n<\/ul>\n
\n
Compliance note: Do not claim a specific SKU is certified unless you have SKU-level proof. Avoid unverified phrases like \u201ccarbon-neutral.\u201d<\/p>\n<\/blockquote>\n
\nUse-Case Recommendations<\/h2>\n
- \n
- \n
Drafts & internal documents:<\/strong> Start with 75 gsm<\/strong>; confirm readability and handling on your main printers.<\/p>\n<\/li>\n
- \n
Duplex reports, proposals, and external-facing docs:<\/strong> Shortlist 80 gsm<\/strong> for better opacity and a more professional feel.<\/p>\n<\/li>\n
- \n
Mixed fleets in CN offices:<\/strong> Standard paper size is A4<\/strong>. If you operate mixed devices, confirm tray size, duplex defaults, and driver profiles before rollout.<\/p>\n<\/li>\n<\/ul>\n
\nHow to Test Before You Buy<\/h2>\n
Request free samples<\/strong> of both 75 gsm<\/strong> and 80 gsm<\/strong> (include any recycled options you plan to trial). Then run this quick in-office check:<\/p>\n
- \n
- \n
Acclimatize<\/strong> unopened reams to office conditions for a few hours.<\/p>\n<\/li>\n
- \n
Choose devices:<\/strong> at least one laser and one inkjet you use most.<\/p>\n<\/li>\n
- \n
Load correctly:<\/strong> fan the stack lightly; align guides; follow any grain arrows on packaging if present.<\/p>\n<\/li>\n
- \n
Print set A (text):<\/strong> 10 duplex pages of mixed body text and headings.<\/p>\n<\/li>\n
- \n
Print set B (coverage):<\/strong> 5 duplex pages with charts\/blocks to simulate heavier coverage.<\/p>\n<\/li>\n
- \n
Score immediately:<\/strong><\/p>\n
- \n
- \n
Legibility<\/strong> (text density, contrast)<\/p>\n<\/li>\n
- \n
Show-through<\/strong> (reverse-side readability)<\/p>\n<\/li>\n
- \n
Curl<\/strong> (after cooling)<\/p>\n<\/li>\n
- \n
Handling<\/strong> (misfeeds, skew)<\/p>\n<\/li>\n
- \n
Surface<\/strong> (visible dusting on rollers\/output path)<\/p>\n<\/li>\n<\/ul>\n<\/li>\n
- \n
Record notes<\/strong> by device and by weight (75 vs 80).<\/p>\n<\/li>\n
- \n
Share results<\/strong> with procurement to shortlist the preferred weight and any recycled line that met your bar.<\/p>\n<\/li>\n<\/ol>\n
\n
Tip: Keep print driver settings identical between tests (paper type, fuser\/ink settings) to make comparisons fair.<\/p>\n<\/blockquote>\n
