Weight: Heavier paper (measured in pounds per ream or gsm) costs more than lighter paper. This is because it requires more raw materials and energy to produce.
Size: Larger paper sizes (e.g., A3 vs. A4) cost more because they use more paper and require larger printing equipment.
Finish: Specialty finishes like gloss or matte can increase printing costs due to the additional processing required.
Color: Colored paper usually costs more than white paper, as it requires additional pigments and processing.
Texture: Textured papers (e.g., embossed, linen) can be more expensive than smooth papers due to their specialized production process.
Opacity: Thicker, more opaque paper (lower opacity percentage) costs more because it requires more material to block light from shining through.
Sustainability: Environmentally friendly paper options, such as recycled paper or paper with Forest Stewardship Council (FSC) certification, may cost more due to higher production standards and sourcing practices.
