A manual with one wrong figure, or a label with one mistranslated warning, does not get corrected — it gets recalled. CRESTEC Thailand is certified to ISO 9001:2015 for quality and ISO 14001:2015 for environmental management, and every job passes through documented review before it leaves us. The checks are not a final inspection; they are built into each stage, and the same discipline is applied to the waste our work produces.

Quality Control

We constantly strive to improve quality by always dedicating ourselves to learning and implementing new technologies in our work processes.

In addition, we successfully fulfill your requests and exceed expectations with the aim of becoming a trustworthy company for our customers and local communities.

How we control quality

At the writing stage

Content is checked against the source specifications and drawings. Anything the source does not answer is raised with your engineers rather than assumed.

At the translation stage

Every translation is reviewed by a second native-speaking linguist against the source, and checked against your glossary and translation memory so terminology stays consistent across every document and every year.

At the layout stage

A native speaker of each language checks the laid-out pages — line breaks, character rendering, text overflow, and image callouts. A file that reads correctly can still be wrong on the page.

At the printing stage

Files are preflighted before plating, and you approve a proof before the run begins. Colour, registration, and finishing are inspected during production.

At delivery

Quantity, revision level, and packing are verified against your order before despatch.

How we manage environmental impact

Printing and packaging produce waste by their nature. Our environmental work is aimed at the largest source of it — printing more than the customer will ever use.

Printing only what is needed

The most wasteful thing in documentation is a warehouse of obsolete manuals, printed in bulk for a model that changed. Our in-house digital printing and our warehousing service let clients print in smaller runs and release stock as they need it. Less capital tied up, less paper thrown away.

Fewer versions, less waste

Structured content and translation memory mean one change is made once and flows through every language. Fewer reprints, fewer scrapped batches.

Reviewed every year

Under our ISO 14001 system, we review the environmental aspects of our operations annually — identifying where our printing, packaging, and warehousing activities affect the environment, and setting targets against them. The review is documented, audited internally, and verified by Intertek.
