FAQ
What is 8K paper size?
8K measures approximately 26 × 38 cm, equivalent to a half-sheet of cai-luh standard paper. 8K is used for large notebooks, art journals, technical drawing books, and presentation notepads.
What is 16K paper size?
16K measures 19 × 26 cm (Taiwan standard) and is approximately equivalent to B5 (17.6 × 25 cm in ISO standard). 16K is the most common size for textbooks, hardcover business notebooks, and corporate planners in the Taiwan and Asia markets.
What is 25K paper size?
25K measures 15 × 21 cm and is the Taiwan industry equivalent of A5 (14.8 × 21 cm in ISO standard). 25K is the most popular size for custom business notebooks, executive planners, and corporate gifting due to its balance of writing space and portability.
How do I convert between 16K and B5?
16K (19 × 26 cm) and B5 (17.6 × 25 cm) are functionally interchangeable for most notebook applications. The 1.4 cm width difference and 1 cm height difference rarely affects user experience. When in doubt, specify B5 for ISO compliance or 16K for Taiwan industry convention.
Which size is best for executive corporate gifts?
For executive gifts, 25K (A5) and 32K (B6) are most popular. 25K provides full daily-planner functionality at 15 × 21 cm. 32K at 13 × 19 cm fits suit jacket pockets and reads as a refined accessory rather than a working notebook.
Notebook:
Any book that can be used for writing, regardless of its binding method, is generally called a notebook.
Planner:
It usually contains dated material, which may cover the current year or span multiple years. It might include monthly planning grids, weekly logs, or daily pages.
Business Planner:
Tailored to the needs of businesses and professionals, it often includes business information in the last few pages, such as volume conversion charts, metro maps, international dialing codes, and time differences, commonly in a binder format for easy page replacement.
Diary:
Typically features lined, gridded, or dotted pages, not limited by date restrictions.
The definitions above are based on the presentation of the inner pages and can be combined with different cover structures. However, care must be taken with the printing, binding, or design details.
Different materials and techniques yield different effects; no method is inherently better or worse. It all depends on what is appropriate and aesthetically pleasing.
Gold and silver foiling appear as colors on the surface without depth. The technique involves transferring colored foils to the appropriate locations using high heat.
Embossing creates a textured imprint with depth but doesn’t alter the original color of the surface, using a heated mold under high pressure.
