Description

本発明は、凹凸模様形成方法に関する。さらに詳しくは、基材上に染料インクでインクジエット印刷により凹部模様を間欠的に印刷し、しかる後、染料インクで印刷した該凹部模様の間欠部に顔料インクでインクジエット印刷により凸部模様を印刷する凹凸模様形成方法に関するもので、具体的には木目模様を表現するのに特に適した凹凸模様形成方法に関するものである。   The present invention relates to a method for forming an uneven pattern. More specifically, a concave pattern is intermittently printed on the base material by ink jet printing with a dye ink, and then a convex pattern is printed on the intermittent part of the concave pattern printed with dye ink by ink jet printing with a pigment ink. More particularly, the present invention relates to a method for forming a concavo-convex pattern that is particularly suitable for expressing a wood grain pattern.

従来から下記特許文献１に示される凹凸模様形成方法は知られている。即ち、基材上に絵柄層を印刷し、この絵柄層上に盛り上げ部（凸部模様）を印刷形成する凹凸模様形成方法である。そして、この盛り上げ部を印刷形成する具体的印刷方法としてインクジエット印刷が示されている。しかしながら、絵柄層上に盛り上げ部を印刷形成することは絵柄層が平滑面である場合、盛り上げ部が動きその位置が一定にならない場合があった。特に凹凸模様が木目模様である場合、木目模様が乱れ、好ましいものでなかった。
特開平１０−１１９２２８号公報 （要約、図１） Conventionally, a method for forming a concavo-convex pattern disclosed in Patent Document 1 below is known. That is, it is a concavo-convex pattern forming method in which a pattern layer is printed on a substrate, and a raised portion (convex pattern) is printed on the pattern layer. Ink jet printing is shown as a specific printing method for printing and forming the raised portion. However, when the raised portion is printed on the pattern layer, when the patterned layer is a smooth surface, the raised portion may move and its position may not be constant. In particular, when the concavo-convex pattern is a grain pattern, the grain pattern is disturbed, which is not preferable.
JP 10-119228 A (Summary, FIG. 1)

本発明は、上記従来例における凹凸模様形成方法の欠点を解決することをその課題とするもので、特に凸模様部が乱れたり、ずれたりする恐れが少ない凹凸模様形成方法を提供せんとするものである。   It is an object of the present invention to solve the drawbacks of the method for forming a concavo-convex pattern in the conventional example described above, and in particular, to provide a method for forming a concavo-convex pattern in which the convex pattern portion is less likely to be disturbed or displaced. It is.

上記課題を解決するために、本発明にかかる凹凸模様形成方法は、基材上に染料インクでインクジエット印刷により凹部模様を印刷し、しかる後、染料インクで印刷した該凹部模様の間欠部に顔料インクでインクジエット印刷により凸部模様を印刷する凹凸模様形成方法であって、基材が露出する低い部分の周囲に染料インクによって形成された高い部分をインクジエット印刷により形成して凹部模様を印刷し、染料インクで印刷した該凹部模様の基材が露出する間欠部にインクジエット印刷により選択的に顔料インクを供給して、上記染料インクによって形成された高い部分の高さより更に高い部分を形成して凸部模様を印刷するものである。 In order to solve the above-described problems, the method for forming a concavo-convex pattern according to the present invention prints a concave pattern on a base material by ink jet printing with a dye ink, and then, on the intermittent portion of the concave pattern printed with the dye ink. A method for forming a concavo-convex pattern in which a convex pattern is printed by ink jet printing with pigment ink, and a concave pattern is formed by forming a high portion formed by dye ink around a low portion where the substrate is exposed by ink jet printing. The pigment ink is selectively supplied by ink jet printing to the intermittent portion where the substrate of the concave pattern printed and printed with the dye ink is exposed, and a portion higher than the height of the high portion formed by the dye ink is provided. It is formed and a convex pattern is printed.

本発明の他の凹凸模様形成方法は染料インクでインクジエット印刷した凹部模様の間欠部に顔料インクでインクジエット印刷により凸部模様を印刷する際に凹部模様の染料インク上に凸部模様の顔料インクを一部重合せしめるものである。   Another method of forming a concavo-convex pattern according to the present invention is to print a convex pattern pigment on a concave pattern dye ink when printing a convex pattern by ink jet printing with a pigment ink on an intermittent part of a concave pattern printed with a dye ink. The ink is partially polymerized.

又、本発明のさらに他の凹凸模様形成方法は基材上に染料インクでインクジエット印刷により凹部模様を印刷し、しかる後、染料インクで印刷した該凹部模様の間欠部に紫外線硬化インクでインクジエット印刷により凸部模様を印刷する凹凸模様形成方法であって、基材が露出する低い部分の周囲に染料インクによって形成された高い部分をインクジエット印刷により形成して凹部模様を印刷し、染料インクで印刷した該凹部模様の基材が露出する間欠部にインクジエット印刷により選択的に紫外線硬化インクを供給して、上記染料インクによって形成された高い部分の高さより更に高い部分を形成して凸部模様を印刷し、紫外線硬化インクを硬化させるものである。
Further, another method for forming a concavo-convex pattern according to the present invention is to print a concave pattern on a base material by ink jet printing with a dye ink, and then to the intermittent part of the concave pattern printed with the dye ink with an ultraviolet curable ink. A method for forming a concavo-convex pattern by printing a convex pattern by jet printing, wherein a high portion formed by dye ink is formed around a low portion where a base material is exposed by ink jet printing, and a concave pattern is printed. The UV curable ink is selectively supplied by ink jet printing to the intermittent part where the substrate of the concave pattern printed with the ink is exposed, and a part higher than the height of the high part formed by the dye ink is formed. A convex pattern is printed and the ultraviolet curable ink is cured.

請求項１に記載の凹凸模様形成方法は、基材上に染料インクでインクジエット印刷により凹部模様を間欠的に印刷するために、基材表面の表面状態が凹部模様部と凹部模様の間欠部とでは異なる。このために凹部模様の間欠部に顔料インクでインクジエット印刷により凸部模様を印刷すると顔料インクは位置ずれを生じ難くすることができるものである。   The concave / convex pattern forming method according to claim 1, in order to intermittently print a concave pattern by ink jet printing with a dye ink on a substrate, the surface state of the substrate surface is a concave pattern portion and an intermittent portion of the concave pattern. And different. For this reason, if a convex part pattern is printed by ink jet printing with pigment ink on the intermittent part of the concave part pattern, the pigment ink can be made difficult to be displaced.

請求項２に記載の凹凸模様形成方法は、基材上に染料インクでインクジエット印刷により凹部模様を間欠的に印刷するために、凹部模様部と凹部模様の間欠部とではわずかであるが段差が生じる。このために凹部模様の間欠部に顔料インクでインクジエット印刷により凸部模様を印刷すると顔料インクはこの段差に阻まれ位置ずれが生じ難くなるものである。そしてこの場合、凹部模様の染料インク上に凸部の模様の顔料インクを一部重合せしめるために基材の地色が凹部模様と凸部模様の間から現れる恐れがないものである。   According to the method for forming a concavo-convex pattern according to claim 2, in order to intermittently print a concave pattern by ink jet printing with a dye ink on a substrate, there is a slight difference in level between the concave pattern part and the intermittent part of the concave pattern. Occurs. For this reason, when a convex pattern is printed by ink jet printing with pigment ink on the intermittent part of the concave pattern, the pigment ink is blocked by this step and is not easily displaced. In this case, since the pigment ink having the convex pattern is partially polymerized on the dye ink having the concave pattern, there is no possibility that the ground color of the base material appears between the concave pattern and the convex pattern.

請求項３に記載の凹凸模様形成方法は、染料インクで印刷した該凹部模様の間欠部に紫外線硬化インクでインクジエット印刷により凸部模様を印刷するために、紫外線硬化インクは短時間で硬化させることができ、凸部模様が位置ずれを生じる恐れが少ないものとなる。   According to the method for forming a concavo-convex pattern according to claim 3, the ultraviolet curable ink is cured in a short time in order to print the convex pattern by ink jet printing with the ultraviolet curable ink on the intermittent part of the concave pattern printed with the dye ink. And the projection pattern is less likely to be misaligned.

以下、本発明の実施形態について図面を参照して、詳細に説明する。図１は本発明の凹凸模様形成方法において、基材に染料インクで凹部模様を印刷した状態を示す断面図、図２は図１に示す凹部模様を印刷した後に凸部模様を印刷した状態を示す断面図、図３は凹凸模様の部分拡大断面図である。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view showing a state in which a concave pattern is printed with a dye ink on a substrate in the method for forming a concave and convex pattern according to the present invention, and FIG. 2 is a state in which a convex pattern is printed after the concave pattern shown in FIG. FIG. 3 is a partially enlarged sectional view of an uneven pattern.

図１において、１は基材、２は染料インクでインクジエット印刷により形成した凹部模様、３は凹部模様２の間欠部である。基材１は合板、中密度繊維板等の木質板、中空押し出しセメント板、パルプセメント板等のセメント板、セラミック板等、特に限定されるものではない。凹部模様２を形成する染料インクは通常使用されるもので良く、インクジエット印刷に適した粘度に溶剤、その他で調整すればよいものである。   In FIG. 1, 1 is a base material, 2 is a concave pattern formed by ink jet printing with dye ink, and 3 is an intermittent part of the concave pattern 2. The base material 1 is not particularly limited, such as a wood board such as a plywood or a medium density fiber board, a cement board such as a hollow extruded cement board or a pulp cement board, or a ceramic board. The dye ink for forming the concave pattern 2 may be a commonly used one, and may be adjusted to a viscosity suitable for ink jet printing with a solvent or the like.

凹部模様２は基材１に間欠的に設けられるもので、間欠部３が形成される。この時、染料インクでインクジエット印刷により形成した凹部模様２と間欠部３とは、凹部模様２は染料インクの塗装面であり、間欠部３は基材１の面であり、異なった状態の面である。基材１に下地塗装をしたときには間欠部３は下地塗装の面となる。   The concave pattern 2 is intermittently provided on the substrate 1, and the intermittent part 3 is formed. At this time, the recessed portion pattern 2 and the intermittent portion 3 formed by ink jet printing with dye ink are the recessed portion pattern 2 is a painted surface of the dye ink, and the intermittent portion 3 is the surface of the base material 1 and are in different states. Surface. When the base material 1 is coated with the base, the intermittent portion 3 becomes the surface of the base coating.

図２は間欠部３に顔料インクでインクジエット印刷により印刷して凸部模様４を形成したものである。この場合、凹部模様２と間欠部３は同一状態の面でないために間欠部３に顔料インクでインクジエット印刷により印刷して形成した凸部模様４を移動し難くすることができる。即ち、間欠部３を顔料インクとなじみの良い表面状態とすれば凸部模様４は移動し難いものとなる。   FIG. 2 shows a pattern 4 formed on the intermittent portion 3 by printing with pigment ink by ink jet printing. In this case, since the concave pattern 2 and the intermittent part 3 are not in the same state, the convex part pattern 4 formed by printing ink jet printing with pigment ink on the intermittent part 3 can be made difficult to move. That is, if the intermittent portion 3 is in a surface state familiar with the pigment ink, the convex portion pattern 4 becomes difficult to move.

又、凹部模様２と間欠部３とは、凹部模様２が染料インクの塗装面であるために、図３に示す如く、わずかであるが凹部模様２が高い段差が生じる。このために、凸部模様４を形成する顔料インクは移動を妨げられ、模様ずれが生じる恐れが少ないものである。この時に、凹部模様２の染料インク上に凸部模様４の顔料インクを一部重合せしめる。かくすることにより、基材１の地色或いは下塗り塗装の色が凹部模様２と凸部模様４の間から現れる恐れがなく外観を損ねるおそれが少ないものである。   Further, the concave pattern 2 and the intermittent part 3 have a slight level difference in the concave pattern 2 as shown in FIG. 3 because the concave pattern 2 is a dye ink coating surface. For this reason, the pigment ink which forms the convex pattern 4 is prevented from moving, and there is little risk of pattern deviation. At this time, the pigment ink of the convex pattern 4 is partially polymerized on the dye ink of the concave pattern 2. By doing so, the background color of the base material 1 or the color of the undercoating is not likely to appear from between the concave pattern 2 and the convex pattern 4, and there is little risk of impairing the appearance.

又、染料インクで印刷した該凹部模様２の間欠部３に紫外線硬化インクでインクジエット印刷により凸部模様４を形成したときは、紫外線硬化インクは短時間で硬化させることができるために模様ずれが生じる前に硬化させることができるものである。   Further, when the convex pattern 4 is formed by ink jet printing with the ultraviolet curable ink on the intermittent part 3 of the concave pattern 2 printed with the dye ink, the ultraviolet curable ink can be cured in a short time, so that the pattern shifts. It can be cured before it occurs.
