Not necessarily.
GSM (Grams per Square Meter) indicates the paper's weight. For instance, ratings of 70gsm, 75gsm, and 80gsm mean the paper weighs 70g, 75g, and 80g per square meter, respectively.

Generally, a higher GSM results in thicker, more rigid paper; however, weight alone does not directly determine quality.

To evaluate A4 paper quality, consider the following factors:
Smoothness: Affects print clarity and toner adhesion.
Stiffness: Affects stability as the paper passes through the printer.
Moisture content: Levels that are too high or too low can increase issues like curling and paper jams.
Whiteness and opacity: Affect the document's visual appearance and the experience of double-sided printing.
Paper feed performance: High-quality office paper should minimize issues such as multi-sheet feeding and paper jams.

Therefore, a high-quality 70gsm A4 paper can easily provide a better user experience than a lower-quality 80gsm paper.

ACO prioritizes flatness, print compatibility, and reliable paper feeding performance. When selecting office paper, rather than simply chasing a higher GSM, it is more important to choose paper with the appropriate weight and consistent quality based on your specific printing needs.
