Sublimation printing error.

How to solve points in a drawing printed in sublimation.
The final art is a PDF file created in Adobe Illustrator.
I have tried attaching transparencies and simplifying the layout and it doesn't work for me. Export in PDF/X-4 or high quality printing.
If you have any idea of a solution, please comment.

Have you tried saving a copy of the PDF using the Illustrator default preset?
