Are there any best practices for creating PDF files in PHP that include special colors like HKS and PMS for printing purposes?

When creating PDF files in PHP that include special colors like HKS and PMS for printing purposes, it is important to ensure that the colors are properly defined in the PDF file. This can be achieved by using the SetFillColor method in the TCPDF library to set the color using the CMYK values for the HKS or PMS color. Additionally, it is recommended to consult the color conversion charts provided by the respective color systems to accurately represent the desired color in the PDF file. 

// Include the TCPDF library
require_once('tcpdf/tcpdf.php');

// Create new TCPDF object
$pdf = new TCPDF();

// Set the color using CMYK values for HKS or PMS color
$pdf->SetFillColor(0, 100, 100, 0); // Example: HKS 43

// Add content to the PDF file
$pdf->AddPage();
$pdf->SetFont('helvetica', 'B', 16);
$pdf->Cell(0, 10, 'Special Color Example', 0, 1, 'C', 1);

// Output the PDF file
$pdf->Output('special_color_example.pdf', 'I');
