Definitions and technical specifications
The cost calculator uses the Incoterm ExWorks. This Incoterm means that the printer
provides the books, in labelled boxes, ready to be loaded onto trucks or into
containers provided by the buyer. The buyer picks up the goods at the
production/storage site and is responsible for all onward transport. Export and
import customs formalities are handled by the buyer. For final procurement
documents, we recommend the Incoterm DPU (delivery at place, unloaded). This will
add approximatively 10 to 15 percent to the costs provided by the cost calculator.
See
Incoterms and Insurance: Guidance for World Bank Procurement of Textbooks
and Reading Books
for more information on Incoterms.
Colour
The cost calculator costs are based on textbooks and books for reading practice
printed in full colour (4/4) and teacher’s guides printed in black and white (1/1). See
page 13 in the
Read@Home Guidance Note Technical Specifications for the
Production of Reading Books
for more information on colour use in instructional
materials.
Type of paper
The costs in the calculator are based on all books being printed with woodfree paper.
Woodfree paper should be used for books that need to be more durable, such as
textbooks, reading books, read-aloud books, big books, library books, and teacher’s
guides. Chemical or woodfree paper does not yellow over time.
For more information on paper type, see page 7 in the
Read@Home Guidance Note
Technical Specifications for the Production of Reading Books
.
Cover coating
The cost calculator is based on all covers being printed on C1S (coated on one side)
paper and all interior pages being printed on C2S (coated on both sides) paper. See
page 16 in the
Read@Home Guidance Note Technical Specifications for the
Production of Reading Books
for more details.
Paper weight
The calculator is based on cover paper weight of 250 gsm and the inside pages at 80
gsm for all books. These are the recommended weights for teacher’s guides,
textbooks, and readers. The cost of books will increase if the gsm is increased.
Cover coating
UV coating should be used for the covers of books that need to be durable, such as
textbooks, reading books, big books/read-aloud books, library books, and teacher
guides. This cost is included in the cost calculator.

Binding
This calculator bases the costs of binding on books being perfect bound with
polyolefin (PO) glue, except reading books with 96 pages or fewer interior pages,
which should be saddle stitched. For more information, see page 17 in the
Read@Home Guidance Note Technical Specifications for the Production of Reading
