Turnaround

Estimated turnaround is 3–5 business days from design preview approval and print start date.
Specialty finishing requires an additional 1–3 business days.

Every effort is made to meet the estimated turnaround. However, delays may occur subject to our production schedule.

Estimated delivery is based on Korean business days. Delivery may be delayed due to public holidays or customs processing in the destination country.

Important Pre-Order NoticeDetails Production GuideDetails

Color

Important information regarding print colors.

1. Printed colors will appear darker and less vivid than on your monitor.

Printing uses CMYK ink mixing to reproduce colors, which cannot identically match monitor colors.

Files submitted in Spot Color or RGB mode will be forcibly converted to CMYK. This may result in colors that differ from your expectations.

Due to the nature of printing, colors may print slightly lighter or darker, and variation between C (Cyan), M (Magenta), Y (Yellow), and K (Black) channels is expected.

Even with the same print data, color differences may occur depending on paper stock and print timing.
Large areas of dark background color may show roller marks.
Even when the same color is used for front and back in the print data, the actual print results may differ slightly.

2. Colors with similar CMYK ratios or sensitive tones may print very differently.

CMYK color deviation may result in significantly different printed colors. Color claims are evaluated based on the submitted print data, not the printed result.

Color deviation example: C=61%, M=52%, Y=52%, K=22%

3. K=100% black is processed with overprint enabled.

If you do not want overprint applied, add 1% of another color to the black, or set the value to K=99%.

< Overprint K=100% >

< Overprint Off >

< Rich Black (C=30% + M=30%) >

< Overprint Example >

4. Patterns and textures require sufficient contrast with the background.

We recommend at least 20–30% color difference from the background.

< Color difference 10% >

< Color difference 20% or more >

< Patterns & Textures >

5. Use caution with text and lines made of mixed CMYK colors.

Slight misregistration between color plates may cause colors to spread or shift. This is more noticeable with thinner text and lines.
On dark backgrounds made of mixed CMYK colors, misregistration can cause thin elements to break up or disappear entirely.
For black text and lines, use pure black (K=100%) only. Do not use a mix of CMYK colors.
Even in a single color, extremely thin text or lines may not reproduce clearly in print.

6. Total CMYK ink coverage should be kept below 250%.

Higher ink density increases the risk of set-off (wet ink transferring onto adjacent sheets).
Pages may stick together, or ink may peel away from the surface.
For deeper tones, increase the K (Black) percentage rather than raising CMY values.
Depending on paper type and printing method, set-off can occur even below 250%.
Very high ink density may result in muddy dark tones or visible roller marks.

Cutting

Important information regarding the cutting process.

A cutting tolerance of ±1–3mm (0.039–0.118 in) is the industry standard and does not constitute grounds for rework.

Large quantities are cut at once, which causes slight shifting.
Keep important content at least 3mm (0.118 in) inside the trim line on all sides.
For catalogs and brochures, at least 5mm (0.197 in) is recommended.
Borders and symmetrical designs cannot be guaranteed to cut evenly. Claims related to this are not accepted.
Shifting may result in slightly diagonal cuts.

Finishing

Important information regarding finishing processes.

A finishing tolerance of ±1–2mm (0.039–0.079 in) is the industry standard and does not constitute grounds for rework.

Die-Cut and Manual Finishing

Due to the nature of high-speed automatic die-cutting, small connection points (nicks) are left on the cut edges to prevent the product from falling out or being damaged.

Die-cutting connection point (nick) example

After die-cutting, a manual finishing process removes any remaining material before shipment.
The number and placement of nicks vary depending on the paper stock, thickness, and shape.
Depending on the paper's texture, thickness, and coating, marks may remain on the cut edges. Thicker paper tends to show more visible marks.
This is a normal result of the manufacturing process, not a product defect. The nicks can be gently removed before use.
Flat-printed products such as business cards, hang tags, and coupons will have nicks remaining on the cut edges.
For envelopes and packaging products, nicks are placed to fold inward during assembly. However, depending on the product structure, some may still be visible.

Size Setup

Select New and set the size for your print product. Set the page size to the trim size, and set the bleed in the Bleed section.

File → New → Document (Ctrl+N)

Intent: Print | Page Size: A4 (210×297mm) | Bleed: 3mm (all sides) | Slug: 0mm

Margin Setup

Set the safety zone in the Margins and Columns dialog. For small products (business cards, hang tags, coupons), use 3mm margins. For larger products (flyers, brochures, catalogs), use 5mm or more.

Layout → Margins and Columns

Margins: 3mm (all sides)

PDF Export

After completing your work, export as PDF with the following settings.

Format: Adobe PDF (Print) | Preset: PDF/X-4:2008 | Marks and Bleeds: Use Document Bleed Settings

Illustrator

Size Setup

Select New and set the size for your print product. Set the width and height based on the safety zone size. The trim size adds 3mm to each side (if using 3mm safety zone). The design size adds 6mm total. For small products (business cards, hang tags, coupons), use 3mm safety zone. For larger products (flyers, brochures, catalogs), use 5mm or more.
